Organization, Consolidation and Presentation of Financial Statements [Abstract]
The Company	Basis of Presentation These unaudited interim condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with U.S. generally accepted accounting principles have been condensed or omitted in these interim statements. Accordingly, these condensed consolidated financial statements are to be read in conjunction with the financial statements and notes included in the Company's Annual Report on Form 10-K for its fiscal year ended March 28, 2015 . These interim statements include all adjustments (consisting of only normal recurring adjustments and accruals) necessary for a fair presentation of results for the interim periods presented. The results for interim periods are not necessarily indicative of the results of operations for the entire year. The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of commitments and contingencies at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results may differ from those estimates. Management believes that the estimates used are reasonable. Significant estimates made by management include: revenue recognition; inventory valuation; product warranty reserves; allowance for doubtful accounts; accrued restructuring costs; share-based compensation; income taxes including the valuation of deferred tax assets; fair value measurements; valuation of cost method equity investments; valuation of long-lived assets; valuation of goodwill; and valuation of acquired technology. There have been no significant changes to the Company's significant accounting policies from those presented in Note 2 “Summary of Significant Accounting Policies” to the consolidated financial statements included in the Company's Annual Report on Form 10-K for its fiscal year ended March 28, 2015 . All references to years or quarters relate to fiscal years or fiscal quarters unless otherwise noted. The three quarters ended January 2, 2016 consisted of a 40-week period as compared to a 39-week period for the three quarters ended December 27, 2014. Similarly, the third quarter of 2016 ended January 2, 2016 was a 14-week period as compared to a 13-week period for the second quarter of 2016 ended September 26, 2015 and the third quarter of 2015 ended December 27, 2014. In the first quarter of 2016, certain prior period amounts were revised to conform to current year presentation. Please see Note 7 "Trade Accounts Receivable" and Note 10 "Accrued Current Liabilities & Other Liabilities" .

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements In January 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-01, "Financial Instruments - Overall (Subtopic 825-10)." ASU 2016-01 enhances the reporting model for financial instruments to provide users of financial statements with more decision-useful information by addressing certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. The amendments simplify certain requirements and also reduce diversity in current practice for other requirements. ASU 2016-01 is effective for public companies' fiscal years beginning after December 15, 2017, which would be the Company's fiscal year ending March 30, 2019, including interim periods within those fiscal years. Except for the early application guidance specifically allowed in ASU 2016-01, early adoption is not permitted. We do not expect the adoption of ASU 2016-01 to have a material effect on our financial position, results of operations or cash flows. In November 2015, the FASB issued ASU 2015-17, "Income Taxes (Topic 740) - Balance Sheet Classification of Deferred Taxes." ASU 2015-17 simplifies the presentation of deferred income taxes, and requires that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. The amendments apply to all entities that present a classified statement of financial position, and aligns the presentation of deferred income tax assets and liabilities with International Financial Reporting Standards ("IFRS") IAS 1. ASU 2015-17 is effective for public companies' financial statements issued for annual periods beginning after December 15, 2016, which would be the Company's fiscal year ending March 31, 2018, and interim periods within those annual periods. Early application is permitted and may be applied either prospectively to all deferred tax liabilities and assets or retrospectively to all periods presented. The Company is currently evaluating the impact of adopting this guidance on its Consolidated Financial Statements and disclosures included within Notes to Consolidated Financial Statements. In August 2015, the FASB issued ASU No. 2015-14, which defers the effective date of ASU No. 2014-09 "Revenue from Contracts with Customers" one year to interim and annual reporting periods beginning after December 15, 2017, which would be the Company's fiscal year ending March 30, 2019. This guidance may be adopted retrospectively or under a modified retrospective method where the cumulative effect is recognized at the date of initial application. The Company is currently evaluating the impact of adopting this guidance on its Consolidated Financial Statements and disclosures included within Notes to Consolidated Financial Statements. In July 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2015-11, “Simplifying the Measurement of Inventory (Topic 330).” ASU 2015-11 simplifies the accounting for the valuation of all inventory not accounted for using the last-in, first-out (“LIFO”) method by prescribing inventory be valued at the lower of cost and net realizable value. ASU 2015-11 is effective for public companies' annual periods, including interim periods within those fiscal years, beginning after December 15, 2016, which would be the Company's fiscal year ending March 31, 2018, on a prospective basis. Early adoption is permitted. We do not expect the adoption of ASU 2015-11 to have a material effect on our financial position, results of operations or cash flows. In April 2015, the FASB issued ASU 2015-05, “Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40).” ASU 2015-05 provides guidance regarding the accounting for a customer's fees paid in a cloud computing arrangement, specifically about whether a cloud computing arrangement includes a software license, and if so, how to account for the software license. ASU 2015-05 is effective for public companies' annual periods, including interim periods, beginning after December 15, 2015, which would be the Company's fiscal year ending April 1, 2017. Early adoption is permitted. We do not expect the adoption of ASU 2015-05 to have a material effect on our financial position, results of operations or cash flows. In June 2014, the FASB issued ASU No. 2014-12, "Compensation - Stock Compensation (Topic 718)." ASU No. 2014-12 addresses accounting for share-based payments when the terms of an award provide that a performance target could be achieved after the requisite service period. ASU 2014-12 indicates that, in such situations, the performance target should be treated as a performance condition and, accordingly, the performance target should not be reflected in estimating the grant-date fair value of the award. Instead, compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved. ASU 2014-12 is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015, which would be the Company's fiscal year ending April 1, 2017. We do not expect the adoption of ASU 2014-12 to have a material effect on our financial position, results of operations or cash flows.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Financial Assets and Liabilities Measured at Fair Value ASC Topic 820 establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include the following: • Level 1 , defined as observable inputs such as quoted prices in active markets for identical assets or liabilities; • Level 2 , defined as inputs that are observable either directly or indirectly such as quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active and other inputs that can be corroborated by observable market data; and • Level 3 , defined as unobservable inputs for which little or no market data exists, therefore requiring an entity to develop its own assumptions. The Company’s fair value hierarchy for its financial assets and liabilities measured at fair value on a recurring basis as of January 2, 2016 and March 28, 2015 was as follows (in thousands): January 2, 2016 Level 1 Level 2 Level 3 Total Cash equivalents: Money market securities $ 3,004 $ — $ — $ 3,004 Commercial paper — 8,948 — 8,948 Government agencies — 1,604 — 1,604 Total cash equivalents $ 3,004 $ 10,552 $ — $ 13,556 Short term investments - available for sale: Government agencies $ — $ 18,836 $ — $ 18,836 Total short-term investments - available for sale $ — $ 18,836 $ — $ 18,836 Forward purchase or (sale) contracts: Japanese Yen $ — $ (58 ) $ — $ (58 ) New Taiwan Dollar — (10 ) — (10 ) Korean Won — (68 ) — (68 ) Euro — (261 ) — (261 ) British Pound — (60 ) — (60 ) Chinese Renminbi — (17 ) — (17 ) Total forward contracts $ — $ (474 ) $ — $ (474 ) Deferred compensation plan assets:* Mutual funds and exchange traded funds $ 1,906 $ — $ — $ 1,906 Money market securities 543 — — 543 Total deferred compensation plan assets $ 2,449 $ — $ — $ 2,449 March 28, 2015 Level 1 Level 2 Level 3 Total Cash equivalents: Money market securities $ 14,280 $ — $ — $ 14,280 Commercial paper — 15,537 — 15,537 Government agencies — 2,702 — 2,702 Total cash equivalents $ 14,280 $ 18,239 $ — $ 32,519 Short term investments - available for sale: Corporate bonds $ — $ 853 $ — $ 853 Municipal bonds — 3,872 — 3,872 Total short-term investments - available for sale $ — $ 4,725 $ — $ 4,725 Forward purchase or (sale) contracts: Japanese Yen $ — $ (7 ) $ — $ (7 ) New Taiwan Dollar — 17 — 17 Korean Won — (44 ) — (44 ) Euro — 277 — 277 British Pound — (133 ) — (133 ) Chinese Renminbi — (34 ) — (34 ) Total forward contracts $ — $ 76 $ — $ 76 Deferred compensation plan assets:* Mutual funds and exchange traded funds $ 1,885 $ — $ — $ 1,885 Money market securities 190 — — 190 Total deferred compensation plan assets $ 2,075 $ — $ — $ 2,075 *These investments represent assets held in trust for our deferred compensation plan For Level 1 assets, the Company utilized quoted prices in active markets for identical assets. For Level 2 assets, exclusive of forward contracts, the Company utilized quoted prices in active markets for similar assets. For forward contracts, spot prices at January 2, 2016 and March 28, 2015 were utilized to calculate fair values. During the first three quarters of 2016 and 2015, there were no transfers between Level 1, 2 or 3 assets. Investments The Company’s investments at January 2, 2016 and March 28, 2015 were as follows (in thousands): Unrealized January 2, 2016 Cost Gain Loss Fair Value Available-for-sale securities (current): Government agencies 20,437 3 — 20,440 Commercial paper 8,948 — — 8,948 Mutual funds and exchange traded funds* 2,454 — (5 ) 2,449 Total Investments $ 31,839 $ 3 $ (5 ) $ 31,837 Unrealized March 28, 2015 Cost Gain Loss Fair Value Available-for-sale securities (current): Commercial paper $ 15,537 $ — $ — $ 15,537 Municipal bonds 3,870 2 — 3,872 Government agencies 2,702 — — 2,702 Corporate bonds 853 — — 853 Mutual funds and exchange traded funds* 1,950 125 — 2,075 Total Investments $ 24,912 $ 127 $ — $ 25,039 *These investments represent assets held in trust for our deferred compensation plan For purposes of determining gross realized gains and losses and reclassification out of accumulated other comprehensive income (loss), the cost of securities sold is based on specific identification. Net unrealized holding gains and losses on current available-for-sale securities included in accumulated other comprehensive income (loss) were insignificant as of January 2, 2016 and March 28, 2015 . Investments with underlying maturities within one year at January 2, 2016 , including cash equivalents, totaled $31.8 million .

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Share-Based Compensation	Share-Based Compensation The Company recognizes expense related to the fair value of its share-based compensation awards using the Black-Scholes model to estimate the fair value of awards on the date of grant, except for unvested restricted stock unit awards (RSUs) which are valued at the fair value of the Company's stock on the date of award. The Company recognizes compensation expense for all share-based compensation awards on a straight-line basis over the requisite service period of the award. Stock-settled stock appreciation rights (SARs) grant the right to receive shares of the Company's stock equivalent to the increase in stock value of a specified number of shares over a specified period of time, divided by the stock price at the time of exercise. The Company uses the Black-Scholes model to estimate the fair value of SARs. Similar to options, SARs are measured at the fair value of the award on the grant date and the expense is recognized on a straight-line basis over the requisite service period of the award. The Company granted a total of 705,700 RSUs and 467,000 SARs during the first three quarters of 2016 , but did not grant any stock options. The Company granted 827,700 RSUs and 634,523 SARs, and zero stock options during the first three quarters of 2015 . Share-based compensation expense was included in the Company’s Condensed Consolidated Statements of Operations as follows: Fiscal quarter ended Three fiscal quarters ended (In thousands) Jan 2, 2016 Dec 27, 2014 Jan 2, 2016 Dec 27, 2014 Cost of sales $ 103 $ 154 $ 347 $ 474 Selling, general and administrative 832 629 2,291 2,096 Research, development and engineering 188 256 613 832 Total share-based compensation expense $ 1,123 $ 1,039 $ 3,251 $ 3,402 The Company does not capitalize share-based compensation costs. As of January 2, 2016 , the Company had $8.1 million of total unrecognized share-based compensation costs, net of estimated forfeitures, which are expected to be recognized over a weighted average period of 2.0 years. The amounts shown in the table above for the fiscal quarter ended January 2, 2016 and three fiscal quarters ended January 2, 2016, do not include $191 thousand and $688 thousand, respectively, in share-based compensation expense related to acquisitions.

Business Combinations [Abstract]
Business Acquisitions	Business Acquisitions Fiscal 2015 On January 15, 2015, the Company acquired all of the outstanding shares of Wuhan Topwin Optoelectronics Technology Co., Ltd. (Topwin), a Chinese manufacturer of laser-based systems and as of March 28, 2015 the company performed a preliminary determination and allocation of purchase price to the identifiable acquired assets and liabilities. In the first quarter of 2016, the Company finalized the determination of purchase price, including the valuation of total consideration and the related contractual adjustments to working capital, and valuation of acquired assets and assumed liabilities. Analysis supporting the purchase price allocation included a valuation of assets and liabilities as of the closing date, an analysis of intangible assets and a detailed review of the opening balance sheet to determine other significant adjustments required to recognize assets and liabilities at fair value. Consideration was comprised of $7.6 million in cash and 748,944 shares of ESI common stock issuable over a three year period, valued at approximately $2.9 million as of the acquisition date. Of the $2.9 million in equity, one-half, or 374,472 shares, is contingent-based consideration and one-half, or 374,472 shares, is non-contingent and will be issued over a three year period beginning June 30, 2015. The contingent consideration is based on future performance of Topwin, as evaluated against targets for net income for each year over a three year period. One-third of the contingent shares will be issued after each year if the target is met for that year; however failing to meet stated targets will result in none of the contingent shares being issued for that year. As of the acquisition date, the fair value of the contingent consideration was estimated to be $0.4 million and the fair value of the 374,472 shares of non-contingent consideration was estimated to be $2.5 million . The fair value of the non-contingent and contingent shares was determined based on the estimated share price as of the issuance date derived through Monte Carlo simulation, discounted back to the acquisition date. The value of the contingent shares included consideration of the estimated probability of attainment of the net income targets. Additionally, the Company will issue, on the same terms described above, approximately 513,328 shares valued at $2.0 million , which, together with cash of $0.2 million , is treated as compensation to a Principal in the Company who was also a former shareholder of Topwin. Compensation expense will be recognized over the Principal's term of employment or related service period required by the purchase agreement through December 31, 2017. In the first three quarters of fiscal 2016, we have recognized approximately $0.7 million in compensation expense related to this agreement, comprised primarily of share-based compensation. The total purchase price of approximately $10.5 million , net of cash acquired, was allocated to the underlying assets acquired and liabilities assumed based on their fair values, as shown in the following table: (In thousands) Accounts receivable $ 454 Inventory 544 Prepaid expense and other current assets 295 Property, plant and equipment 23 Acquired intangibles 3,618 Goodwill 7,445 Accounts payable and other accrued liabilities (1,859 ) Total purchase price, net of cash acquired $ 10,520 The acquisition is expected to enable the Company to gain entry into the low total-cost-of-ownership solutions market in China and the goodwill of approximately $7.4 million recognized as a result of the acquisition was assigned to the Topwin reporting unit. The premium paid over the fair value of the individual assets acquired and liabilities assumed reflects the Company’s view that this acquisition was subject to competitive bidding and that it provided the Company with innovative design and manufacturing capabilities for laser-based manufacturing solutions across a variety of complementary applications, together with direct access to local China market, supply chain and opto-electronics knowledge center. None of the goodwill is expected to be deductible for tax purposes. As a result of the acquisition, the Company recorded approximately $4.9 million of identifiable assets, including $3.6 million of identifiable intangible assets and $1.9 million of identifiable liabilities. The acquired intangible assets consist primarily of $3.5 million of developed technology and will be amortized over their useful lives, which range from one to ten years. In the first three quarters of 2016, the Company incurred approximately $0.2 million in acquisition-related costs, which were included in Selling, general and administrative expenses in the Consolidated Statements of Operations. In 2015, the Company incurred approximately $0.8 million in acquisition-related costs, which were included in Selling, general and administrative expenses in the Consolidated Statements of Operations. The operating results of this acquisition are included in the Company’s results of operations since the date of acquisition. Pro forma financial information has not been provided for the acquisition of Topwin as it was not material to the Company’s operations and overall financial position.

Commitments and Contingencies Disclosure [Text Block]	Commitments & Contingencies On March 20, 2015, the Company entered into a loan and security agreement ("Loan Agreement") with Silicon Valley Bank, as lender. The Loan Agreement provides for a senior secured asset-based revolving credit facility (the “Credit Facility”) with up to $30 million available on a revolving basis, including a $15 million sublimit for letters of credit. The credit agreement expires March 20, 2018. At January 2, 2016 , we had no revolving loans or letters of credit outstanding under our Credit Facility, we were in compliance with all covenants, and were not in default under the Loan Agreement. The commitment fee on the amount of unused credit was 0.3 percent. We mitigate credit risk by transacting with highly rated counterparties for foreign exchange contracts, letters of credit and other transactions where counterparty risk is a factor. We have evaluated the non-performance risks associated with our lenders and other parties and believe them to be insignificant. From time to time we may be party to litigation arising in the normal course of business. Currently we are not party to any litigation we believe would have a material adverse effect on our financial position, results of operations, or cash flows.

Our chief operating decision maker is our Chief Executive Officer. Prior to the fourth quarter of 2015, we operated in one segment, high-technology manufacturing equipment, which was comprised of products that were classified in three groups: interconnect and micromachining, semiconductor and component. As a result of changes in our go-to-market strategies, common customer characteristics, and information utilized to manage our business, we realigned our products into two segments. Since the fourth quarter 2015 the Company has operated in two segments, Component Processing and Micromachining.

Restructuring and Cost Management Plans	Restructuring and Cost Management Plans In March 2015, as a part of the plan to streamline manufacturing and development activities, the Company initiated a restructuring plan that included the closure of the assembly plant and development center located in Chelmsford, Massachusetts, which was part of our Component Processing segment. The original estimated completion date of the plan was the end of fiscal 2016 at a total estimated pre-tax cost of $5.5 million. See the Company's Form 10-K for the year ended March 28, 2015 for additional information related to restructuring and cost management plans. Net restructuring costs related to the above mentioned restructuring plan were $2.6 million in the first three quarters of 2016 and $5.6 million from the inception of the plan. Included in these costs were write-offs of leasehold improvements associated with the abandoned manufacturing facility, employee severance and related payments, and other wind-down costs. As of January 2, 2016 , most of the restructuring activities have been completed, and we expect to pay the remaining costs and accrued expenses primarily related to severance and employee benefits by the end of 2016. At January 2, 2016 and March 28, 2015 , the amount of unpaid restructuring costs included in accrued liabilities was $1.0 million and $2.0 million , respectively.
