Organization and Nature of Operations: [Abstract] | |
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block] | Basis of Presentation The accompanying interim unaudited condensed consolidated financial statements have been prepared by Rudolph Technologies, Inc. (the “Company” or “Rudolph”) and in the opinion of management reflect all adjustments, consisting of normal recurring accruals, necessary for their fair presentation in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). Preparing financial statements requires management to make estimates and assumptions that affect amounts reported in the financial statements and accompanying notes. Actual amounts could differ materially from reported amounts. The interim results for the three and six month periods ended June 30, 2016 are not necessarily indicative of results to be expected for the entire year or any future periods. This interim financial information should be read in conjunction with the financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015 (“2015 10-K”) filed with the Securities and Exchange Commission (“SEC”). The accompanying condensed consolidated balance sheet at December 31, 2015 has been derived from the audited consolidated financial statements included in the 2015 10-K. Reclassifications Certain immaterial prior period amounts have been reclassified to conform to the current financial statement presentation. Debt Issuance Costs: In the first quarter of 2016, the Company adopted Accounting Standards Update (ASU) No. 2015-03, “Interest - Imputation of Interest (Subtopic 835-30), Simplifying the Presentation of Debt Issuance Costs,” which requires entities to present debt issuance costs related to a debt liability as a direct deduction from the carrying amount of that debt liability on the balance sheet as opposed to being presented as a deferred charge. For all periods presented in this Form 10-Q for the quarter ended June 30, 2016 , unamortized debt issuance costs related to the Company’s convertible senior notes are reported on the Consolidated Balance Sheets as a reduction of the carrying value of the related debt. Prior to adoption, the Company reported the unamortized debt issuance costs in “Other Assets” on the Consolidated Balance Sheets. As of December 31, 2015 , the change in presentation resulted in a reduction of “Other Assets” of $261 and a corresponding decrease in “Convertible Senior Notes” with no impact on the Company’s Consolidated Statements of Operations. Recent Accounting Pronouncements In June 2016, the Financial Accounting Standards Board (FASB) issued ASU No. 2016-13, “Financial Instruments – Credit Losses (Topic 326)”, which introduces new guidance for the accounting for credit losses on instruments within its scope. Given the breadth of that scope, the new ASU will impact both financial services and non-financial services entities. The standard is effective for fiscal years beginning after December 15, 2020. The Company is in the process of determining the adoption method as well as the effects the adoption of ASU No. 2016-13 will have on its consolidated financial position, results of operations, and cash flows. In March 2016, the FASB issued ASU No. 2016-09, “Compensation - Stock Compensation (Topic 718), Improvements to Employee Share-Based Payment Accounting”. The standard was issued as part of the Simplification Initiative which involves several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The standard is effective for annual periods beginning after December 15, 2017, and interim periods within annual periods beginning after December 15, 2018. The Company is in the process of determining the adoption method as well as the effects the adoption of ASU No. 2016-09 will have on its consolidated financial position, results of operations, and cash flows. In March 2016, the FASB issued ASU No. 2016-07, “Investments-Equity Method and Joint Ventures (Topic 323).” The standard was issued as part of the Simplification Initiative which eliminates the requirement that when an investment qualifies for use of the equity method as a result of an increase in the level of ownership interest or degree of influence, an investor must adjust the investment, results of operations, and retained earnings retroactively on a step-by-step basis as if the equity method has been in effect during all previous periods that the investment had been held. The standard is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2016. The Company is in the process of evaluating the effects the adoption of ASU No. 2016-07 will have on its consolidated financial position, results of operations, and cash flows. In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842).” The standard requires that lessees will be required to recognize assets and liabilities on the balance sheet for the rights and obligations created by all leases with terms of more than 12 months. ASU No. 2016-02 also will require disclosures designed to give financial statement users information on the amount, timing, and uncertainty of cash flows arising from leases. These disclosures include qualitative and quantitative information. The standard is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2018 with earlier adoption permitted. The Company is in the process of evaluating the effects the adoption of ASU No. 2016-02 will have on its consolidated financial position, results of operations, and cash flows. In January 2016, the FASB issued ASU 2016-01, “Financial Instruments – Overall: Recognition and Measurement of Financial Assets and Financial Liabilities.” The pronouncement requires equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income, requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes, requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset, and eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost. The standard is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. The Company is in the process of evaluating the effects the adoption of ASU No. 2016-01 will have on its consolidated financial position, results of operations, and cash flows. In July 2015, the FASB issued ASU No. 2015-11, “Inventory (Topic 330), Simplifying the Measurement of Inventory.” This ASU is intended to simplify subsequent measurement of inventory. An entity should measure inventory within the scope of this ASU at the lower of cost and net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable cost of completion, disposal, and transportation. The standard is effective for annual periods and interim periods within those annual periods, beginning after December 15, 2016. The adoption of ASU 2015-11 is not expected to have a material effect on the Company’s consolidated financial position, results of operations, and cash flows. In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606).” ASU No. 2014-09 outlines a comprehensive revenue recognition model and supersedes most current revenue recognition guidance as amended. In July 2015, the FASB deferred for one year the effective date of the new revenue standard. The standard is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017 with earlier adoption permitted. ASU No. 2014-09 allows for two methods of adoption: (a) “full retrospective” adoption, meaning the standard is applied to all periods presented, or (b) “modified retrospective” adoption, meaning the cumulative effect of applying ASU No. 2014-09 is recognized as an adjustment to the 2018 opening retained earnings balance. The Company is in the process of determining the adoption method as well as the effects the adoption of ASU No. 2014-09 will have on its consolidated financial position, results of operations, and cash flows. |
Fair Value Measurements

Fair Value Measurements [Abstract] | |
Fair Value Disclosures [Text Block] | Fair Value Measurements The Company applies a three-level valuation hierarchy for fair value measurements. This hierarchy prioritizes the inputs into three broad levels. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the asset or liability. Level 3 inputs are unobservable inputs based on management’s assumptions used to measure assets and liabilities at fair value. A financial asset’s or liability’s fair value measurement classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. The following tables provide the assets and liabilities carried at fair value measured on a recurring basis at June 30, 2016 and December 31, 2015 : Fair Value Measurements Using Carrying Quoted Prices in Significant Other Significant June 30, 2016 Assets: Available-for-sale debt securities: Municipal notes and bonds $ 95,819 $ — $ 95,819 $ — Corporate bonds 842 — 842 — Total Assets $ 96,661 $ — $ 96,661 $ — Liabilities: Foreign currency forward contracts 385 $ — $ 385 $ — Contingent consideration - acquisitions 3,726 — — 3,726 Total Liabilities $ 4,111 $ — $ 385 $ 3,726 December 31, 2015 Assets: Available-for-sale debt securities: Municipal notes and bonds $ 116,089 $ — $ 116,089 $ — Corporate bonds 835 — 835 — Total Assets $ 116,924 $ — $ 116,924 $ — Liabilities: Foreign currency forward contracts $ 85 $ — $ 85 $ — Contingent consideration - acquisitions 3,703 — — 3,703 Total Liabilities $ 3,788 $ — $ 85 $ 3,703 The Company’s investments classified as Level 2 are valued using observable inputs to quoted market prices, benchmark yields, reported trades, broker/dealer quotes or alternative pricing sources with reasonable levels of price transparency. The foreign currency forward contracts are primarily measured based on the foreign currency spot and forward rates quoted by the banks or foreign currency dealers. Available-for-sale debt securities prices are obtained from third party pricing providers, which models prices utilizing the above observable inputs, for each asset class. Level 3 liabilities consisted of contingent consideration related to an acquisition for which the Company uses a discounted cash flow model to value these liabilities. The Level 3 assumptions used in the discounted cash flow model for the contingent consideration included projected revenues, estimates of discount rates of 9.1% and timing of cash flows. A significant decrease in the projected revenues or increase in discount rates could result in a significantly lower fair value measurement for the contingent consideration. This table presents a reconciliation for all liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3) for the six months ended June 30, 2016 : Fair Value Measurements Using Balance at December 31, 2015 $ 3,703 Additions — Total loss included in selling, general and administrative expense 117 Payments (94 ) Transfers into (out of) Level 3 — Balance at June 30, 2016 $ 3,726 See Note 3 for additional discussion regarding the fair value of the Company’s marketable securities. Fair Value of Other Financial Instruments The carrying value of cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximates fair value because of the short-term maturity of these instruments. The estimated fair value of these obligations is based, primarily, on a market approach, comparing the Company’s interest rates to those rates the Company believes it would reasonably receive upon re-entry into the market. Judgment is required to estimate the fair value, using available market information and appropriate valuation methods. The Company’s convertible senior notes are not publicly traded. The estimated fair value of the Company’s convertible senior notes was valued using a discounted cash flow model. The Level 3 assumptions, based on data available at the valuation date used in preparing the discounted cash flow model, included estimates of interest rates, timing and amount of cash flows and expected holding periods of the convertible senior notes. The fair value of the contingent interest associated with the convertible senior notes is valued quarterly using the present value under an expected cash flow model incorporating the probabilities of the contingent events occurring. The following table reflects information pertaining to the Company’s convertible senior notes: June 30, 2016 December 31, 2015 Net carrying value of convertible senior notes $ 59,885 $ 57,846 Estimated fair value of convertible senior notes $ 60,996 $ 60,630 Estimated interest rate used in discounted cash flow model 5.0 % 5.0 % Fair value of contingent interest $ — $ — |

Marketable Securities [Abstract] | |
Marketable Securities [Text Block] | Marketable Securities The Company has evaluated its investment policies and determined that all of its investment securities are to be classified as available-for-sale. Available-for-sale securities are carried at fair value, with the unrealized gains and losses reported in Stockholders’ Equity under the caption “Accumulated other comprehensive loss.” Realized gains and losses on available-for-sale securities are included in “Other expense (income)” in the Condensed Consolidated Statements of Operations. The Company records other-than-temporary impairment charges for its available-for-sale investments when it intends to sell the securities, it is more-likely-than not that it will be required to sell the securities before a recovery, or when it does not expect to recover the entire amortized cost basis of the securities. The cost of securities sold is based on the specific identification method. The Company has determined that the gross unrealized losses on its marketable securities at June 30, 2016 and December 31, 2015 are temporary in nature. The Company reviews its investment portfolio to identify and evaluate investments that have indications of possible impairment. Factors considered in determining whether a loss is other-than-temporary include the length of time and extent to which fair value has been less than the cost basis, credit quality and the Company’s ability and intent to hold the investment for a period of time sufficient to allow for any anticipated recovery in market value. At June 30, 2016 and December 31, 2015 , marketable securities are categorized as follows: Amortized Cost Gross Unrealized Holding Gains Gross Unrealized Holding Losses Fair Value June 30, 2016 Municipal notes and bonds $ 95,796 $ 27 $ 4 $ 95,819 Corporate bonds 841 1 — 842 Total marketable securities $ 96,637 $ 28 $ 4 $ 96,661 December 31, 2015 Municipal notes and bonds $ 116,086 $ 18 $ 15 $ 116,089 Corporate bonds 838 — 3 835 Total marketable securities $ 116,924 $ 18 $ 18 $ 116,924 The amortized cost and estimated fair value of marketable securities classified by the maturity date listed on the security, regardless of the Condensed Consolidated Balance Sheet classification, is as follows at June 30, 2016 and December 31, 2015 : June 30, 2016 December 31, 2015 Amortized Cost Fair Value Amortized Cost Fair Value Due within one year $ 87,562 $ 87,574 $ 113,542 $ 113,549 Due after one through five years 9,075 9,087 3,382 3,375 Due after five through ten years — — — — Due after ten years — — — — Total marketable securities $ 96,637 $ 96,661 $ 116,924 $ 116,924 The following table summarizes the estimated fair value and gross unrealized holding losses of marketable securities, aggregated by investment instrument and period of time in an unrealized loss position at June 30, 2016 and December 31, 2015 : Unrealized Loss Position For Less Than 12 Months Unrealized Loss Position For Greater Than 12 Months Fair Value Gross Unrealized Losses Fair Value Gross Unrealized Losses June 30, 2016 Municipal notes and bonds $ 21,501 $ 4 $ — $ — Total $ 21,501 $ 4 $ — $ — December 31, 2015 Municipal notes and bonds $ 52,638 $ 15 $ 305 $ 1 Corporate bonds 835 3 — — Total $ 53,473 $ 18 $ 305 $ 1 See Note 2 for additional discussion regarding the fair value of the Company’s marketable securities. |

Derivative Instruments and Hedging Activities [Abstract] | |
Derivative Instruments and Hedging Activities Disclosure [Text Block] | Derivative Instruments and Hedging Activities The Company, when it considers it to be appropriate, enters into forward contracts to hedge the economic exposures arising from foreign currency denominated transactions. At June 30, 2016 and December 31, 2015 , these contracts included the future sale of Japanese Yen to purchase U.S. dollars. Derivative instruments are recognized as either prepaid expenses and other current assets or other current liabilities in the Condensed Consolidated Balance Sheets and are measured at fair value. The foreign currency forward contracts were entered into by the Company’s Japanese subsidiary to economically hedge a portion of certain intercompany obligations. The forward contracts are not designated as hedges for accounting purposes and decreases in the fair value of $300 and $203 for the six month periods ended June 30, 2016 and 2015, respectively, are recorded within the caption “Other expense (income)” in the Condensed Consolidated Statements of Operations. The dollar equivalent of the U.S. dollar forward contracts and related fair values as of June 30, 2016 and December 31, 2015 were as follows: June 30, 2016 December 31, 2015 Notional amount $ 3,785 $ 5,423 Fair value of liability $ 385 $ 85 |

Debt Obligations [Abstract] | |
Debt Disclosure [Text Block] | Debt Obligations On July 25, 2011 , the Company issued $60,000 aggregate principal amount of 3.75% Convertible Senior Notes due 2016 (the “Notes”) at par. The Notes were issued pursuant to an indenture, dated as of July 25, 2011 , between the Company and Bank of New York Mellon Trust Company, N.A., as Trustee, which includes a form of Note. The Notes provide for the payment of interest semi-annually in arrears on January 15 and July 15 of each year, beginning January 15, 2012 , at an annual rate of 3.75% and will mature on July 15, 2016 , unless earlier converted or repurchased. The Notes may be converted, under certain circumstances, based on an initial conversion rate of 77.241 shares of Company common stock per $1 principal amount of Notes, which represents an initial conversion price of approximately $12.95 per share. Concurrently with the issuance of the Notes, the Company purchased a convertible note hedge and sold a warrant. Each of the convertible note hedge and warrant transactions were entered into with an affiliate of the initial purchaser of the Notes. The convertible note hedge is intended to reduce the potential future dilution to the Company’s common stock associated with the conversion of the Notes. However, the warrant transaction will have a dilutive effect on the Company’s earnings per share to the extent that the price of the Company’s common stock exceeds the strike price of the warrant. The strike price of the warrant is $17.00 per share subject to adjustment in accordance with the terms of the agreement. The net proceeds to the Company from the sale of the Notes, including the convertible note hedge and warrant, were $50,249 . The following table reflects the net carrying value of the Notes: June 30, 2016 December 31, 2015 Convertible senior notes $ 60,000 $ 60,000 Less: Unamortized interest discount 100 1,893 Less: Unamortized debt issuance costs 15 261 Net carrying value of convertible senior notes $ 59,885 $ 57,846 The following table presents the amount of interest cost recognized relating to the Notes during the three and six months ended June 30, 2016 and June 30, 2015 : Three Months Ended June 30, Six Months Ended June 30, 2016 2015 2016 2015 Contractual interest coupon $ 563 $ 563 $ 1,125 $ 1,125 Amortization of interest discount 899 815 1,793 1,626 Amortization of debt issuance costs 123 104 246 207 Total interest cost recognized $ 1,585 $ 1,482 $ 3,164 $ 2,958 The remaining bond discount of $100 and debt issuance costs of $15 relating to the Notes, as of June 30, 2016 , will be amortized over the remaining life of the Notes.

Commitments and Contingencies [Abstract] | |
Commitments and Contingencies Disclosure [Text Block] | Commitments and Contingencies Warranty Reserves The Company generally provides a warranty on its products for a period of 12 to 15 months against defects in material and workmanship. The Company estimates the costs that may be incurred during the warranty period and records a liability in the amount of such costs at the time revenue is recognized. The Company’s estimate is based primarily on historical experience. The Company periodically assesses the adequacy of its recorded warranty liabilities and adjusts the amounts as necessary. Settlements of warranty reserves are generally associated with sales that occurred during the 12 to 15 months prior to the quarter-end and warranty accruals are related to sales during the year. Changes in the Company’s warranty reserves are as follows: Six Months Ended June 30, 2016 2015 Balance, beginning of the period $ 1,894 $ 1,574 Accruals 1,261 1,300 Less: Usage 1,319 1,051 Balance, end of the period $ 1,836 $ 1,823 Warranty reserves are reported in the Condensed Consolidated Balance Sheets within the caption “Accounts payable and accrued liabilities.” Legal Matters From time to time, the Company is subject to legal proceedings and claims in the ordinary course of business. The Company’s 2015 10-K reflects the status of the Company’s litigation with Integrated Technology Corporation (“ITC”) and Camtek, Ltd. (“Camtek”). The following reflects the material developments during the six months ended June 30, 2016 with regard to these matters. Integrated Technology Corporation v. Rudolph Technologies, Inc., No. CV-06-2182 (PHX-ROS) : This matter is fully resolved with the sole exception of the issue of remanded attorney’s fees which were set by the U.S. District Court for the District of Arizona (the “AZ District Court”) at $3,252 . A hearing regarding the Company’s appeal of this order was held on October 6, 2015 before the U.S. Federal Court of Appeals (the “Court of Appeals”). The Court of Appeals issued a ruling that the award was improperly established, vacated the amount of the award and remanded the matter back to the AZ District Court for a determination of a proper fee award. The Company believes that it has meritorious defenses regarding this issue and intends to continue to vigorously prosecute the matter. The $3,252 is held in escrow and is recorded in “Prepaid expenses and other current assets” in the Condensed Consolidated Balance Sheet at June 30, 2016 . The corresponding liability is recorded under the caption “Other current liabilities” in the Condensed Consolidated Balance Sheet at June 30, 2016 . The Company expects this to be the maximum liability reasonably possible for the attorney’s fees, excluding interest, for this lawsuit with respect to both the pre-August 2007 and the post-August 2007 tools which were the subject of this action. August Technology Corporation and Rudolph Technologies, Inc. v. Camtek, Ltd., No. 05-CV-01396 (JRT/FLN) : Subsequent to the ruling by the U.S. District Court for the District of Minnesota (the “MN District Court”) in the Company’s favor that Camtek’s Falcon tools continue to infringe the Company’s patent under the revised claim construction of the patent determined by the Court of Appeals, the MN District Court, on February 9, 2015, issued an Order granting the Company’s Motion for Final Judgment, reinstating the original damages and applying prejudgment interest for a total award of $14,512 . In addition, the MN District Court issued a permanent injunction against Camtek from “making, using, selling and offering to sell any of its Falcon machines and any machines that are colorable imitations thereof in the United States, intended for sale and use within the United States, until the expiration of the ‘6,298 patent,” which is projected to be in 2020. While, in March of 2015, Camtek filed an appeal with the Court of Appeals challenging the MN District Court’s ruling, the Court of Appeals denied Camtek’s appeal on February 3, 2016, affirming both the infringement ruling and the damages and interest totaling approximately $14,632 assessed against Camtek by the MN District Court, the payment of which is guaranteed by a supersedeas bond. All of Camtek’s rights to appeal the final judgment have now expired. On March 14, 2016 the Company filed its request to the MN District Court to release payment under the bond which was granted by the MN District Court on June 24, 2016. Payment by Camtek is currently being facilitated. The Company recorded the judgment in “Prepaid expenses and other current assets” in the Condensed Consolidated Balance Sheets as of June 30, 2016 as the gain contingency was realized upon completion of the appeal process. August Technology Corporation and Rudolph Technologies, Inc. v. Camtek, Ltd., No. 10-CV-2202 (MJD/FLN) : With regard to the Company’s subsequently filed lawsuit against Camtek in the MN District Court alleging infringement of its U.S. Patent No. 7,729,528, this lawsuit continues to be stayed pending resolution of a re-examination petition filed by Camtek with the U.S. Patent and Trademark Office. Rudolph Technologies, Inc. v. Camtek, Ltd., No. 15-CV-1246 (ADM/BRT) : On March 12, 2015, the Company filed and served on Camtek a complaint asserting infringement of Rudolph ‘6,298 patent by Camtek’s Eagle product with the MN District Court. On April 21, 2015, the Company filed a Motion for Preliminary Injunction to enjoin Camtek’s sale of the Eagle device in the United States which is currently pending. On or about April 20, 2015, Camtek filed a complaint in the U.S. District Court for the District of New Jersey (the “NJ District Court”) seeking a declaratory judgment challenging the jurisdiction and venue of the Minnesota court and seeking to have the NJ District Court find that the ‘6,298 patent is not infringed and, in the alternative, that the ‘6,298 patent is invalid. On August 26, 2015, the MN District Court ruled that Minnesota jurisdiction was appropriate for this matter while at the same time denying the Company’s Motion for Preliminary Injunction. Camtek’s complaint filed in the NJ District Court was subsequently dismissed. This matter is currently in discovery phase of the litigation. Line of Credit The Company has a credit agreement with a bank that provides for a line of credit which is secured by the marketable securities the Company has with the bank. The Company is permitted to borrow up to a percentage of the value of the marketable securities held at the time the line of credit is accessed. The Company has not utilized the line of credit to date. |

Income Tax Disclosure [Text Block] | Income Taxes The following table provides details of income taxes: Three Months Ended Six Months Ended June 30, June 30, 2016 2015 2016 2015 Income before income taxes $ 10,593 $ 8,656 $ 30,154 $ 11,753 Provision for income taxes $ 2,992 $ 2,629 $ 8,614 $ 3,878 Effective tax rate 28.2 % 30.4 % 28.6 % 33.0 % The income tax provision for the three and six months ended June 30, 2016 was computed based on the Company’s annual forecast of profit by jurisdiction and forecasted effective tax rate for the year. The changes in the Company’s effective tax rate for the three and six months ended June 30, 2016 compared to the same period for the prior year are primarily due to changes in the mix of forecasted earnings by jurisdictions, additional IRC Section 199 Manufacturing deduction expected to be generated for the year ended December 31, 2016 and the availability of the research and development credit for the full year 2016 as compared to the enactment of the credit in the fourth quarter 2015. The Company currently has a partial valuation allowance recorded against certain foreign and state net operating loss and credit carryforwards where the realizability of such deferred tax assets is substantially in doubt. Each quarter, the Company assesses the likelihood that it will be able to recover its deferred tax assets. The Company considers available evidence, both positive and negative, including forecasted earnings in assessing the need for a valuation allowance. As a result of the Company’s analysis, it concluded that it is more likely than not that a portion of its deferred tax assets will not be realized. Therefore, the Company continues to provide a valuation allowance against certain deferred tax assets. The Company continues to monitor available evidence and may reverse some or all of the remaining valuation allowance in future periods, if appropriate. The Company has a recorded valuation allowance against certain of its deferred tax assets of $2,205 as of June 30, 2016 and December 31, 2015. |

Earnings (Loss) Per Share [Abstract] | |
Earnings Per Share [Text Block] | Earnings Per Share Basic earnings per share is calculated using the weighted average number of shares of common stock outstanding during the period. Diluted earnings per share is computed in the same manner and also gives effect to all dilutive common equivalent shares outstanding during the period. Potential common shares that would have the effect of increasing diluted earnings per share are considered to be anti-dilutive. In accordance with U.S. GAAP, these shares were not included in calculating diluted earnings per share. For the six months ended June 30, 2016 , the weighted average number of stock options and restricted stock units excluded from the computation of diluted earnings per share were 78 and 0 , respectively. For the six months ended June 30, 2015 , the weighted average number of stock options and restricted stock units totaling 260 and 0 , respectively, were excluded from the computation of diluted earnings per share. For the six months ended June 30, 2016 , diluted earnings per share-weighted average shares outstanding included the effect resulting from assumed conversion of the Notes and warrants. For the six months ended June 30, 2015 diluted earnings per share-weighted average shares outstanding do not include any effect resulting from assumed conversion of the Notes and warrants at June 30, 2016 as their impact was anti-dilutive. The Company’s basic and diluted earnings per share amounts are as follows: Three Months Ended June 30, Six Months Ended June 30, 2016 2015 2016 2015 Numerator: Net income $ 7,601 $ 6,027 $ 21,540 $ 7,875 Denominator: Basic earnings per share - weighted average shares outstanding 30,779 31,663 30,869 31,724 Effect of potential dilutive securities: Employee stock options and restricted stock units - dilutive shares 563 676 630 649 Convertible senior notes - dilutive shares 412 — 206 — Diluted earnings per share - weighted average shares outstanding 31,754 32,339 31,705 32,373 Earnings per share: Basic $ 0.25 $ 0.19 $ 0.70 $ 0.25 Diluted $ 0.24 $ 0.19 $ 0.68 $ 0.24 |

Subsequent Events [Text Block] | Subsequent Events On July 15, 2016, the Company redeemed all of its outstanding 3.75% Convertible Senior Notes with an aggregate principle amount of $60,000 . Under the terms of the indenture, holders of the Notes were paid cash up to the aggregate principal amount of the notes and shares of common stock for the remainder of our conversion, with any fracional shares paid in cash. As a result of this redemption, the Company eliminated its debt and will have cash savings in annual interest payments of $2,250 . The conversion resulted in the issuance of 540 shares of common stock to the bondholders, but resulted in no dilution to Rudolph shareholders as these shares were covered by a convertible note hedge that was entered into by the Company in 2011 at the time of issuance of the notes.
