Accounting Policies [Abstract]
Basis of Presentation	1. Basis of Presentation Novanta Inc. and its subsidiaries (collectively referred to as “Novanta”, the “Company”, “we”, “us”, “our”) is a leading global supplier of core technology solutions that give medical and advanced industrial original equipment manufacturers (“OEMs”) a competitive advantage. Novanta combines deep proprietary technology expertise and competencies in photonics, vision and precision motion with a proven ability to solve complex technical challenges. This enables Novanta to engineer core components and sub-systems that deliver extreme precision and performance, tailored to the customers’ demanding applications. The accompanying unaudited interim consolidated financial statements have been prepared by the Company in United States (“U.S.”) dollars and pursuant to the rules and regulations of the United States Securities and Exchange Commission (“SEC”), the instructions to Form 10-Q and the provisions of Regulation S-X pertaining to interim financial statements. Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the U.S. have been condensed or omitted. The interim consolidated financial statements and notes included in this report should be read in conjunction with the consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021. In the opinion of management, these interim consolidated financial statements include all adjustments and accruals of a normal and recurring nature necessary to fairly state the results of the interim periods presented. The results for interim periods are not necessarily indicative of results to be expected for the full year or for any future periods. The Company’s unaudited interim consolidated financial statements are prepared for each quarterly period ending on the Friday closest to the end of the calendar quarter, with the exception of the fourth quarter which always ends on December 31. Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities as of the dates of the financial statements, and the reported amounts of revenue and expenses during the reporting periods. Estimates and assumptions are reviewed on an on-going basis and the effects of revisions are reflected in the period in which such revisions are deemed to be necessary. The Company evaluates its estimates based on historical experience, current conditions, and various other assumptions that it believes are reasonable under the circumstances. Actual results could differ significantly from these estimates. Recent Accounting Pronouncements The following table provides a brief description of recent Accounting Standards Updates (“ASU”) issued by the Financial Accounting Standards Board (“FASB”): Standard Description Effective Date Effect on the Financial Statements or Other Significant Matters In March 2020, the FASB issued ASU 2020-04, “Reference rate reform (Topic 848): Facilitation of the effects of reference rate reform on financial reporting.” ASU 2020-04 provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. Upon issuance. Adoption of ASU 2020-04 is elective. In March 2022, the Company amended the Third Amended and Restated Credit Agreement and replaced LIBOR with SOFR as the new reference rate for U.S. dollar borrowings. The ASU did not have any impact on the Company’s consolidated financial statements. In October 2021, the FASB issued ASU 2021-08, “Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers.” ASU 2021-08 requires that entities recognize and measure contract assets and liabilities acquired in a business combination in accordance with ASC 606, “Revenue from Contracts with Customers”. ASU 2021-08 also applies to contract assets or liabilities from other contracts to which the provisions of ASC 606 apply. The amendments in ASU 2021-08 do not affect the accounting for other assets or liabilities that may arise from revenue contracts with customers in accordance with ASC 606, such as refund liabilities, or in a business combination, such as customer-related intangible assets and contract-based intangible assets. January 1, 2023. Early adoption is permitted. The Company early adopted ASU 2021-08 as of January 1, 2022. The adoption of ASU 2021-08 did not have any material impact on the Company’s consolidated financial statements.

Revenue

Revenue From Contract With Customer [Abstract]
Revenue	2. Revenue The Company recognizes revenue when control of promised goods or services is transferred to customers. The transfer of control generally occurs upon shipment when title and risk of loss pass to the customer. The vast majority of the Company’s revenue is generated from the sale of distinct products. Revenue is measured as the amount of consideration the Company expects to receive in exchange for such products, which is generally at contractually stated prices. Sales taxes and value added taxes collected concurrently with revenue generating activities are excluded from revenue. Performance Obligations Substantially all of the Company’s revenue is recognized at a point in time, upon shipment, rather than over time. At the request of its customers, the Company may perform professional services, generally for the maintenance and repair of products previously sold to those customers and for engineering services. Professional services for the maintenance and repair of products are typically short in duration, mostly less than one month, and generally involve a single distinct performance obligation. The related revenue is recognized at a point in time when control transfers to the customer upon completion of professional services. The consideration expected to be received in exchange for such services is typically the contractually stated amount. Certain engineering services are longer in duration and the related revenue is recognized over time. As the Company’s right to payment from a customer is based on the value of engineering services performed, the Company recognizes revenue based on the corresponding value to the customer from the Company’s performance completed to date. Revenue from engineering services aggregated to less than 3% of the Company’s consolidated revenue during the three months ended April 1, 2022 and April 2, 2021. The Company occasionally sells separately priced non-standard/extended warranty services or preventative maintenance plans with the sale of products. The transfer of control over the service plans is over time. The Company recognizes the related revenue ratably over the terms of the service plans. The transaction price of a contract is allocated to each performance obligation based on its relative standalone selling price. Standalone selling prices are generally determined based on the prices charged to customers or using the expected cost plus a margin. Shipping & Handling Costs The Company accounts for shipping and handling activities that occur after the transfer of control over the related goods as fulfillment activities rather than performance obligations. Shipping and handling fees charged to customers are recognized as revenue and the related costs are recorded in cost of revenue at the time of transfer of control. Warranties The Company generally provides warranties for its products. The standard warranty period is typically 12 months to 36 months. The Company recognizes liabilities associated with standard warranty periods for its products in accordance with the provisions of ASC 450, “Contingencies,” as the Company has the ability to ascertain the likelihood of the liabilities and can reasonably estimate the amount of the liabilities. A provision for the estimated cost related to standard warranties is recorded as cost of revenue at the time revenue is recognized. The Company’s estimate of the costs to service the warranty obligations is based on historical experience and expectations of future conditions. To the extent that the Company’s experience in warranty claims or costs associated with servicing those claims differ from the original estimates, revisions to the estimated warranty liabilities are recorded at that time, with offsetting adjustments to cost of revenue. Practical Expedients and Exemptions The Company expenses incremental direct costs of obtaining a contract when incurred if the expected amortization period is one year or less. These costs are recorded within selling, general and administrative expenses in the consolidated statement of operations. The Company does not adjust the promised amount of consideration for the effects of a financing component because the transfer of a promised good to a customer and the customer’s payment for that good are typically one year or less. The Company does not disclose the value of the remaining performance obligation for contracts with an original expected length of one year or less. Contract Liabilities Contract liabilities consist of deferred revenue and advance payments from customers, including amounts that are refundable. These contract liabilities are classified as either current or long-term liabilities in the consolidated balance sheet based on the timing of when the Company expects to recognize the related revenue. As of April 1, 2022 and December 31, 2021, contract liabilities were $7.5 million and $7.3 million, respectively, and are included in accrued expenses and other current liabilities and other liabilities in the accompanying consolidated balance sheets. The increase in the contract liability balance during the three months ended April 1, 2022 is primarily due to cash payments received in advance of satisfying performance obligations, partially offset by $3.2 million of revenue recognized during the period that was included in the contract liability balance as of December 31, 2021. Disaggregated Revenue See Note 15 for the Company’s disaggregation of revenue by segment, geography and end market.

Earnings Per Share [Abstract]
Earnings per Common Share	4. Earnings per Common Share Basic earnings per common share is computed by dividing consolidated net income by the weighted average number of common shares outstanding during the period. For diluted earnings per common share, the denominator includes the dilutive effect of outstanding common share equivalents. For the three months ended April 1, 2022 and April 2, 2021, respectively, weighted average shares outstanding for the diluted earnings per common share included the dilutive effect of outstanding restricted stock units, stock options, and relative total shareholder return performance-based restricted stock units (“TSR-PSUs”), determined using the treasury stock method. The dilutive effects of market-based contingently issuable shares are included in the weighted average common share calculation based on the number of shares, if any, that would be issuable as of the end of the reporting period, assuming the end of the reporting period is also the end of the performance period. Dilutive effects of attainment-based contingently issuable shares granted to the former Laser Quantum Limited (“Laser Quantum”) noncontrolling interest shareholders, non-GAAP EPS performance-based restricted stock units (“EPS-PSUs”), operating cash flow performance-based restricted stock units (“OCF-PSUs”), and performance-based restricted stock units granted to the ATI Industrial Automation, Inc. (“ATI”) employees (“ATI-PSUs”) are included in the weighted average common share calculation when the performance targets have been achieved based on the cumulative achievement against the performance targets as of the end of each reporting period. The following table sets forth the computation of basic and diluted earnings per common share (amounts in thousands, except per share data): Three April 1, April 2, 2022 2021 Numerators: Consolidated net income $ 18,820 $ 11,310 Denominators: Weighted average common shares outstanding— basic 35,538 35,279 Dilutive potential common shares 243 510 Weighted average common shares outstanding— diluted 35,781 35,789 Antidilutive potential common shares excluded from above 93 27 Earnings per Common Share: Basic $ 0.53 $ 0.32 Diluted $ 0.53 $ 0.32 For the three months ended April 1, 2022, 36 thousand EPS-PSUs and 37 thousand OCF-PSUs granted to certain members of the executive management team, 55 thousand ATI-PSUs, and 213 thousand shares of restricted stock issued to the former Laser Quantum non-controlling interest share holders are considered contingently issuable shares and were excluded from the calculation of the denominator as the contingent conditions had not been met as of April 1 , 202 2 . For the three months ended April 2, 2021, 46 thousand EPS-PSUs and 37 thousand OCF-PSUs granted to certain members of the executive management team, and 213 thousand shares of restricted stock issued to the former Laser Quantum non-controlling interest shareholders were considered contingently issuable shares and were excluded from the calculation of the denominator as the contingent conditions had not been met as of April 2, 2021.

Fair Value Measurements

Fair Value Measurements	3 Months Ended
	Apr. 01, 2022
Fair Value Disclosures [Abstract]
Fair Value Measurements	5. Fair Value Measurements ASC 820, “Fair Value Measurements,” establishes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the third is considered unobservable: • Level 1: Quoted prices for identical assets or liabilities in active markets which the Company can access • Level 2: Observable inputs other than those described in Level 1 • Level 3: Unobservable inputs Current Assets and Liabilities The Company’s cash equivalents are highly liquid investments with original maturities of three months or less, which represent an asset the Company measures at fair value on a recurring basis. The Company determines the fair value of cash equivalents using a market approach based on quoted prices in active markets. The fair values of cash, accounts receivable, income taxes receivable, accounts payable, income taxes payable and accrued expenses and other current liabilities approximate their carrying values because of their short-term nature. Foreign Currency Contracts The Company addresses market risks from changes in foreign currency exchange rates through a risk management program that includes the use of derivative financial instruments to mitigate certain balance sheet foreign currency transaction exposures. The Company uses foreign currency forward contracts as a part of its strategy to manage exposures related to foreign currency denominated monetary assets and liabilities. The fair value of these foreign currency forward contracts is reported either in other current assets or in other current liabilities as of the end of the period. Contingent Considerations On August 30, 2021, the Company acquired ATI. Under the purchase and sale agreement for the ATI acquisition, the former shareholders of ATI are eligible to receive contingent consideration based on ATI’s fiscal year 2021 Adjusted EBITDA, as defined in the purchase and sale agreement. The contingent consideration will be payable in 2022. The preliminary fair value of the contingent consideration was determined based on the Monte Carlo valuation method and was recorded as part of the purchase price as of the acquisition date. Once the fair value of the contingent consideration is finalized, subsequent changes in the estimated fair value are recorded in the consolidated statement of operations in restructuring, acquisition, and related costs until the liability is fully settled. The fair value of the contingent consideration was $44.0 million as of December 31, 2021. There were no changes in the fair value of the contingent consideration during the three months ended April 1, 2022. On July 31, 2019, the Company acquired ARGES GmbH (“ARGES”). Under the purchase and sale agreement for the ARGES acquisition, the former owner of ARGES is eligible to receive contingent consideration based on the achievement of certain revenue targets by the Company from August 2019 through December 2026. The undiscounted range of possible contingent consideration is zero to €10.0 million ($11.1 million). If the revenue targets are achieved, the contingent consideration would be payable annually with the first payment due in the first quarter of 2021. The estimated fair value of the contingent consideration of €7.1 million ($7.9 million) was determined based on the Monte Carlo valuation method and was recorded as part of the purchase price as of the acquisition date. Subsequent changes in the estimated fair value of the contingent consideration liability are recorded in the consolidated statement of operations in restructuring, acquisition, and related costs until the liability is fully settled. During 2020, the fair value of the contingent consideration was adjusted to €4.1 million ($5.1 million). During 2021, the fair value of the contingent consideration was adjusted to €3.3 million ($3.8 million). The Company made the first installment payment of €0.4 million ($0.4 million) in March 2021 and the second installment payment of € 0.3 million ($ 0.4 million) in March 2022 . These installment payments are reported as cash outflows from financing activities in the consolidated statement of cash flows for the respective periods. Based on the revenue performance and revenue projections as of April 1, 2022, the fair value of the remaining contingent consideration was adjusted to € 1.4 million ($ 1.5 million). There were no other changes in the fair value of the contingent consideration during the three months ended April 1 , 202 2 . On April 16, 2019, the Company acquired Ingenia CAT, S.L. (“Ingenia”). Under the purchase and sale agreement for the Ingenia acquisition, the shareholders of Ingenia are eligible to receive contingent consideration based on the achievement of certain revenue targets by the Company from April 2019 through March 2022. The undiscounted range of possible contingent consideration is zero to €8.0 million ($9.0 million). If the revenue targets are achieved, the contingent consideration would be payable in cash in three annual installments from 2020 to 2022. The estimated fair value of the contingent consideration of €5.8 million ($6.6 million) was determined based on the Monte Carlo valuation method and was recorded as part of the purchase price as of the acquisition date. Subsequent changes in the estimated fair value of the contingent consideration liability are recorded in the consolidated statement of operations in restructuring, acquisition, and related costs until the liability is fully settled. During 2020, the fair value of the contingent consideration was adjusted to €2.3 million ($2.9 million). During 2021, the fair value of the contingent consideration was adjusted to €1.5 million ($1.7 million).The Company made the first installment payment of €1.0 million ($1.1 million) in May 2020 and the second installment payment of €1.2 million ($1.4 million) in May 2021. These installment payments are reported as cash outflows from financing activities in the consolidated statement of cash flows for the respective periods. Based on the revenue performance as of April 1, 2022, the end of the relevant performance period, the fair value of the remaining contingent consideration was adjusted to On December 14, 2016, the Company acquired certain video signal processing and management technologies used in medical visualization solutions. Under the purchase and sale agreement, the former owners are eligible to receive contingent consideration based on the achievement of certain revenue targets by the Company from 2018 to 2021 from products utilizing the acquired technologies. The undiscounted range of possible contingent consideration is zero to €5.5 million ($6.6 million). If the revenue targets are achieved, the contingent consideration would be payable in cash in four installments from 2019 to 2022. As the acquired assets did not meet the definition of a business, the fair value of the contingent consideration is recognized when probable and estimable and is capitalized as part of the cost of the acquired assets. Subsequent changes in the estimated fair value of this contingent liability are recorded as adjustments to the carrying value of the assets acquired and amortized over the remaining useful life of the underlying assets. Based on revenue achievements against the target, the Company had recognized an aggregate fair value of €5.5 million ($6.3 million) of the acquired intangible assets as of April 1, 2022. The Company made the first installment payment of €2.4 million ($2.6 million) in February 2020, the second installment payment of €1.8 million ($2.2 million) in February 2021, and the final installment payment of €1.3 million ($1.5 million) in March 2022. The installment payments have been reported as cash outflows from investing activities in the consolidated statements of cash flows.

The Senior Credit Facilities mature in December 2024 and includes an uncommitted accordion option pursuant to which the commitments under the revolving credit facility may be increased by an additional $200.0 million in aggregate, subject to certain customary conditions. The outstanding principal balance under the term loan facility is payable in quarterly installments of €1.1 million beginning in March 2020, with the remaining balance due upon maturity. The Company may make additional principal payments at any time, which will reduce the next quarterly installment payment due. Borrowings under the revolving credit facility may be repaid at any time through March 2027. The Company made principal payments of €1.1 million ($1.2 million) towards its term loan and $10.4 million towards its revolving credit facility during the three months ended April 1, 2022.

Leases [Abstract]
Leases	10. Leases Most leases held by the Company expire between 2022 and 2036. In the U.K., where longer lease terms are more common, the Company has a land lease that extends through 2078. Certain leases include one or more options to renew, with renewal terms that can extend the lease term from one to 10 years, and options to terminate the leases within one year. The exercise of lease renewal or termination options is at the Company’s sole discretion; therefore, the majority of renewal options to extend the lease terms are not included in the Company’s right-of-use assets and operating lease liabilities as they are not reasonably certain of being exercised. The Company regularly evaluates the renewal options and includes the renewal periods in the lease term when they are reasonably certain of being exercised. The depreciable lives of the right-of-use assets and leasehold improvements are limited to the expected lease terms.

Preferred and Common Shares and Share-Based Compensation	11. Preferred and Common Shares and Share-Based Compensation Preferred Shares In May 2021, the Company’s shareholders approved a special resolution to amend the Company’s articles to authorize up to 7.0 million preferred shares for future issuance. The Company’s Board of Directors is authorized to designate and issue one or more series of preferred shares, fix the rights, preferences and designation, as deemed necessary or advisable, relating to the preferred shares, provided that no shares of any series may be entitled to more than one vote per share. As of April 1, 2022, no preferred shares had been issued and outstanding. Common Share Repurchases In October 2018, the Company’s Board of Directors approved a share repurchase plan (the “2018 Repurchase Plan”), authorizing the repurchase of $25.0 million worth of the Company’s common shares. In February 2020, the Company’s Board of Directors approved a new share repurchase plan (the “2020 Repurchase Plan”), authorizing the repurchase of an additional $50.0 million worth of the Company’s common shares. As of April 1, 2022, the Company had $59.5 million available for future share repurchases under these share repurchase plans. Share-Based Compensation Expense The table below summarizes share-based compensation expense recorded in the consolidated statements of operations (in thousands): Three April 1, April 2, 2022 2021 Selling, general and administrative $ 5,201 $ 4,929 Research and development and engineering 700 727 Cost of revenue 873 988 Total share-based compensation expense $ 6,774 $ 6,644 Share-based compensation expense reported in selling, general and administrative expenses included expenses related to restricted stock units and deferred stock units granted to the members of the Company’s Board of Directors of $1.0 million and $1.1 million during the three months ended April 1, 2022 and April 2, 2021, respectively. Restricted Stock Units and Deferred Stock Units The Company’s restricted stock units (“RSUs”) have generally been issued with vesting periods ranging from zero to five years and vest based solely on service conditions. Accordingly, the Company recognizes compensation expense on a straight-line basis over the requisite service period. The Company reduces the compensation expense by an estimated forfeiture rate which is based on an ticipated forfeitures and historical forfeiture experience. Deferred stock units (“DSUs”) are granted to the members of the Company’s Board of Directors. Compensation expense associated with the DSUs is recognized in full on the date of grant, as the DSUs are fully vested and non-forfeitable upon grant. There were 90 thousand and 91 thousand DSUs outstanding as of April 1, 2022 and December 31, 2021, respectively. Outstanding DSUs are included in the calculation of weighted average basic shares outstanding for the respective periods. The table below summarizes activities relating to RSUs and DSUs issued and outstanding under the Company’s Amended and Restated 2010 Incentive Plan during the three months ended April 1, 2022: Shares (In thousands) Weighted Average Grant Date Fair Value Unvested at December 31, 2021 292 $ 115.42 Granted 81 $ 139.46 Vested (95 ) $ 108.01 Forfeited (1 ) $ 127.39 Unvested at April 1, 2022 277 $ 124.92 Expected to vest as of April 1, 2022 254 The total fair value of RSUs and DSUs that vested during the three months ended April 1, 2022 was $12.9 million based on the market price of the underlying shares on the date of vesting. Performance Stock Units The Company typically grants two types of performance-based stock awards, EPS-PSUs and TSR-PSUs, to certain members of the executive management team on an annual basis. Both types of performance-based restricted stock units generally cliff vest on the first day following the end of the three-year The number of common shares to be issued upon settlement following vesting of the EPS-PSUs is determined based on the Company’s cumulative non-GAAP EPS over a three-year performance period against the performance targets established by the Company’s Board of Directors at the time of grant and will be in the range of zero to 200% of the target number of shares. The Company recognizes compensation expense ratably over the performance period based on the number of shares that are deemed probable of vesting at the end of the three-year performance cycle. This probability assessment is performed quarterly and the cumulative effect of a change in the estimated compensation expense, if any, is recognized in the consolidated statement of operations in the period in which such determination is made. The number of common shares to be issued upon settlement following vesting of the TSR-PSUs is determined based on the relative market performance of the Company’s common shares compared to the Russell 2000 Index over a three-year In January 2022, the Company granted ATI-PSUs to ATI employees. The number of common shares to be issued upon settlement following vesting is determined based on a performance matrix for a four-year The table below summarizes the activities relating to the performance-based awards issued and outstanding under the Company’s Amended and Restated 2010 Incentive Plan during the three months ended April 1, 2022: Shares (In thousands) Weighted Average Grant Date Fair Value Unvested at December 31, 2021 162 $ 122.26 Granted 102 $ 158.59 Vested (41 ) $ 108.58 Forfeited (1 ) $ 173.77 Unvested at April 1, 2022 222 $ 144.25 Expected to vest as of April 1, 2022 213 The unvested PSUs are shown at target in the table above. As of April 1, 2022, the maximum number of common shares to be earned under these PSU grants was approximately 350 thousand shares. The total fair value of PSUs that vested during the three months ended April 1, 2022 was $7.2 million based on the market price of the underlying common shares on the date of vesting. The fair value of the TSR-PSUs at the date of grant was estimated using the Monte Carlo valuation method with the following assumptions: Three Months Ended April 1, 2022 Grant-date stock price $ 135.86 Expected volatility 40.70 % Risk-free interest rate 1.69 % Expected annual dividend yield — Fair value $ 141.52 Stock Options In February 2022, the Company granted 40 thousand stock options to certain members of the executive management team to purchase common shares of the Company at a strike price equal to the closing market price of the Company’s common shares on the date of grant.

Income Tax Disclosure [Abstract]
Income Taxes	12. Income Taxes The Company determines its estimated annual effective tax rate at the end of each interim period based on full-year forecasted pre-tax income and facts known at that time. The estimated annual effective tax rate is applied to the year-to-date pre-tax income at the end of each interim period with the cumulative effect of any changes in the estimated annual effective tax rate being recorded in the period in which the changes are determined. The tax effect of significant unusual items is reflected in the period in which they occur. Since the Company is incorporated in Canada, it is required to use Canada’s statutory tax rate of 29.0% in the determination of the estimated annual effective tax rate. The Company maintains a valuation allowance on balances of certain U.S. state net operating losses and certain non-U.S. tax attributes that the Company has determined are more likely than not to be realized. A valuation allowance is required when, based upon an assessment of various factors, including recent operating loss history, anticipated future earnings, and prudent and reasonable tax planning strategies, it is more likely than not that some portion of the deferred tax assets will not be realized. In conjunction with the Company’s ongoing review of its actual results and anticipated future earnings, the Company continuously reassesses the possibility of adding a new or additional valuation allowance or releasing the valuation allowance currently in place on its deferred tax assets. The Company’s effective tax rate of 9.1% for the three months ended April 1, 2022 differs from the Canadian statutory tax rate of 29.0% primarily due to the mix of income earned in jurisdictions with varying tax rates, estimated deductions for Foreign Derived Intangible Income, U.K. patent box deductions, other tax credits, and windfall tax benefits upon vesting of certain share-based compensation awards, partially offset by disallowed compensation and uncertain tax position accruals. For the three months ended April 1, 2022, the windfall tax benefits upon vesting of certain share-based compensation awards had a benefit of 3% on the Company’s effective tax rate. The Company’s effective tax rate of (20.8%) for the three months ended April 2, 2021 differs from the Canadian statutory tax rate of 29.0% primarily due to the mix of income earned in jurisdictions with varying tax rates, estimated deductions for Foreign Derived Intangible Income, U.K. patent box deductions, other tax credits, and windfall tax benefits upon vesting of certain share-based compensation awards during the period. For the three months ended April 2, 2021, the windfall tax benefits upon vesting of certain share-based compensation awards had a benefit of 35.9% on the Company’s effective tax rate.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	14. Commitments and Contingencies Purchase Commitments There have been no material changes to the Company’s purchase commitments since December 31, 2021. Legal Contingencies The Company is subject to various legal proceedings and claims that arise in the ordinary course of business. The Company reviews the status of each significant matter and assesses the potential financial exposure on a quarterly basis. If the potential loss from any claim or legal proceeding is considered probable and the amount can be reasonably estimated, the Company accrues a liability for the estimated loss. Significant judgment is required in both the determination of probability and the determination as to whether an exposure is reasonably estimable. Because of uncertainties related to these matters, accruals are based only on the best information available as of the date of the consolidated balance sheet. As additional information becomes available, the Company reassesses the potential liability related to any pending claims and litigations and may revise its estimates. When a material loss contingency is reasonably possible but not probable, the Company does not record a liability, but instead discloses the nature and the amount of the claim, and an estimate of the potential loss or a range of potential losses, if such an estimate can be made. Legal fees are expensed as incurred. The Company does not believe that the outcome of these claims will have a material adverse effect on its consolidated financial statements but there can be no assurance that any such claims, or any similar claims, would not have a material adverse effect on the consolidated financial statements. Guarantees and Indemnifications In the normal course of its operations, the Company executes agreements that provide for indemnification and guarantees to counterparties in transactions such as business dispositions, sale of assets, sale of products and operating leases. Additionally, the by-laws of the Company require it to indemnify certain current or former directors, officers, and employees of the Company against expenses incurred by them in connection with each proceeding in which they are involved as a result of serving or having served in certain capacities. Indemnification is not available with respect to a proceeding as to which it has been adjudicated that the person did not act in good faith in the reasonable belief that the action was in the best interests of the Company. Certain of the Company’s officers and directors are also a party to indemnification agreements with the Company. These indemnification agreements provide, among other things, that the director or officer shall be indemnified to the fullest extent permitted by applicable law against all expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred by such director or officer in connection with any proceeding by reason of their relationship with the Company. In addition, the indemnification agreements provide for the advancement of expenses incurred by such director or officer in connection with any proceeding covered by the indemnification agreement, subject to the conditions set forth therein and to the extent such advancement is not prohibited by law. The indemnification agreements also set out the procedures for determining entitlement to indemnification, the requirements relating to notice and defense of claims for which indemnification is sought, the procedures for enforcement of indemnification rights, the limitations on and exclusions from indemnification, and the minimum levels of directors and officers liability insurance to be maintained by the Company.

Use of Estimates	Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities as of the dates of the financial statements, and the reported amounts of revenue and expenses during the reporting periods. Estimates and assumptions are reviewed on an on-going basis and the effects of revisions are reflected in the period in which such revisions are deemed to be necessary. The Company evaluates its estimates based on historical experience, current conditions, and various other assumptions that it believes are reasonable under the circumstances. Actual results could differ significantly from these estimates.
Recent Accounting Pronouncements	Recent Accounting Pronouncements The following table provides a brief description of recent Accounting Standards Updates (“ASU”) issued by the Financial Accounting Standards Board (“FASB”): Standard Description Effective Date Effect on the Financial Statements or Other Significant Matters In March 2020, the FASB issued ASU 2020-04, “Reference rate reform (Topic 848): Facilitation of the effects of reference rate reform on financial reporting.” ASU 2020-04 provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. Upon issuance. Adoption of ASU 2020-04 is elective. In March 2022, the Company amended the Third Amended and Restated Credit Agreement and replaced LIBOR with SOFR as the new reference rate for U.S. dollar borrowings. The ASU did not have any impact on the Company’s consolidated financial statements. In October 2021, the FASB issued ASU 2021-08, “Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers.” ASU 2021-08 requires that entities recognize and measure contract assets and liabilities acquired in a business combination in accordance with ASC 606, “Revenue from Contracts with Customers”. ASU 2021-08 also applies to contract assets or liabilities from other contracts to which the provisions of ASC 606 apply. The amendments in ASU 2021-08 do not affect the accounting for other assets or liabilities that may arise from revenue contracts with customers in accordance with ASC 606, such as refund liabilities, or in a business combination, such as customer-related intangible assets and contract-based intangible assets. January 1, 2023. Early adoption is permitted. The Company early adopted ASU 2021-08 as of January 1, 2022. The adoption of ASU 2021-08 did not have any material impact on the Company’s consolidated financial statements.
Revenue Recognition	The Company recognizes revenue when control of promised goods or services is transferred to customers. The transfer of control generally occurs upon shipment when title and risk of loss pass to the customer. The vast majority of the Company’s revenue is generated from the sale of distinct products. Revenue is measured as the amount of consideration the Company expects to receive in exchange for such products, which is generally at contractually stated prices. Sales taxes and value added taxes collected concurrently with revenue generating activities are excluded from revenue. Performance Obligations Substantially all of the Company’s revenue is recognized at a point in time, upon shipment, rather than over time. At the request of its customers, the Company may perform professional services, generally for the maintenance and repair of products previously sold to those customers and for engineering services. Professional services for the maintenance and repair of products are typically short in duration, mostly less than one month, and generally involve a single distinct performance obligation. The related revenue is recognized at a point in time when control transfers to the customer upon completion of professional services. The consideration expected to be received in exchange for such services is typically the contractually stated amount. Certain engineering services are longer in duration and the related revenue is recognized over time. As the Company’s right to payment from a customer is based on the value of engineering services performed, the Company recognizes revenue based on the corresponding value to the customer from the Company’s performance completed to date. Revenue from engineering services aggregated to less than 3% of the Company’s consolidated revenue during the three months ended April 1, 2022 and April 2, 2021. The Company occasionally sells separately priced non-standard/extended warranty services or preventative maintenance plans with the sale of products. The transfer of control over the service plans is over time. The Company recognizes the related revenue ratably over the terms of the service plans. The transaction price of a contract is allocated to each performance obligation based on its relative standalone selling price. Standalone selling prices are generally determined based on the prices charged to customers or using the expected cost plus a margin. Shipping & Handling Costs The Company accounts for shipping and handling activities that occur after the transfer of control over the related goods as fulfillment activities rather than performance obligations. Shipping and handling fees charged to customers are recognized as revenue and the related costs are recorded in cost of revenue at the time of transfer of control. Warranties The Company generally provides warranties for its products. The standard warranty period is typically 12 months to 36 months. The Company recognizes liabilities associated with standard warranty periods for its products in accordance with the provisions of ASC 450, “Contingencies,” as the Company has the ability to ascertain the likelihood of the liabilities and can reasonably estimate the amount of the liabilities. A provision for the estimated cost related to standard warranties is recorded as cost of revenue at the time revenue is recognized. The Company’s estimate of the costs to service the warranty obligations is based on historical experience and expectations of future conditions. To the extent that the Company’s experience in warranty claims or costs associated with servicing those claims differ from the original estimates, revisions to the estimated warranty liabilities are recorded at that time, with offsetting adjustments to cost of revenue. Practical Expedients and Exemptions The Company expenses incremental direct costs of obtaining a contract when incurred if the expected amortization period is one year or less. These costs are recorded within selling, general and administrative expenses in the consolidated statement of operations. The Company does not adjust the promised amount of consideration for the effects of a financing component because the transfer of a promised good to a customer and the customer’s payment for that good are typically one year or less. The Company does not disclose the value of the remaining performance obligation for contracts with an original expected length of one year or less. Contract Liabilities Contract liabilities consist of deferred revenue and advance payments from customers, including amounts that are refundable. These contract liabilities are classified as either current or long-term liabilities in the consolidated balance sheet based on the timing of when the Company expects to recognize the related revenue. As of April 1, 2022 and December 31, 2021, contract liabilities were $7.5 million and $7.3 million, respectively, and are included in accrued expenses and other current liabilities and other liabilities in the accompanying consolidated balance sheets. The increase in the contract liability balance during the three months ended April 1, 2022 is primarily due to cash payments received in advance of satisfying performance obligations, partially offset by $3.2 million of revenue recognized during the period that was included in the contract liability balance as of December 31, 2021. Disaggregated Revenue See Note 15 for the Company’s disaggregation of revenue by segment, geography and end market.
