Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Accounting [Text Block]	BASIS OF PRESENTATION The condensed consolidated financial statements of Kopin Corporation (the Company) as of April 1, 2017 and for the three months ended April 1, 2017 and March 26, 2016 are unaudited and include all adjustments which, in the opinion of management, are necessary to present fairly the results of operations for the periods then ended. These condensed consolidated financial statements should be read in conjunction with the Company’s financial statements and notes thereto, included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 . The results of the Company's operations for any interim period are not necessarily indicative of the results of the Company's operations for any other interim period or for a full fiscal year. Recently Issued Accounting Pronouncements Revenue from Contracts with Customers In May 2014 , the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers (Topic 606) . This new standard outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. In addition, ASU 2014-09 provides guidance on accounting for certain revenue-related costs including, but not limited to, when to capitalize costs associated with obtaining and fulfilling a contract. The underlying principle is to recognize revenue when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. The new standard also requires entities to enhance disclosures about the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The Company anticipates applying the guidance in ASU 2014-09 after January 1, 2018 . The Company is currently evaluating the expected impact of this new guidance on its consolidated financial statements and available adoption methods. Leases In February 2016 , the FASB issued Accounting Standards Update No. 2016-02 (Topic 842) Leases . Topic 842 supersedes the lease recognition requirements in Accounting Standards Codification Topic 840, "Leases". Under Topic 842, lessees are required to recognize assets and liabilities on the balance sheet for most leases and provide enhanced disclosures. Leases will continue to be classified as either finance or operating. Topic 842 is effective for annual reporting periods, and interim periods within those years beginning after December 15, 2018 . Entities are required to use a modified retrospective approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements, and there are certain optional practical expedients that an entity may elect to apply. Full retrospective application is prohibited and early adoption by public entities is permitted. The Company is currently evaluating the expected impact of this new guidance on its consolidated financial statements. The Company has not yet made any decision on the timing of adoption or method of adoption with respect to the optional practical expedients. Business Combinations In January 2017 , the FASB issued ASU 2017-01 , Business Combinations (Topic 805). The new guidance clarifies the definition of a business that an entity uses to determine whether a transaction should be accounted for as an asset acquisition (or disposal) or a business combination. The guidance is expected to cause fewer acquired sets of assets (and liabilities) to be identified as businesses. The guidance is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2017 . Early adoption is permitted for transactions that meet certain requirements. The Company is evaluating the impact this standard will have on its financial statements. Intangibles- Goodwill and Other In January 2017 , the FASB issued ASU 2017-04, Intangibles- Goodwill and Other (Topic 350). The new guidance simplifies the accounting for goodwill impairments by eliminating Step 2 from the goodwill impairment test. The guidance requires, among other things, recognition of an impairment loss when the fair value of a reporting unit exceeds its carrying amount. The loss recognized is limited to the total amount of goodwill allocated to that reporting unit. The guidance is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2019 . Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017 . The Company is evaluating the impact this standard will have on its financial statements.

Cash and Equivalents and Marketable Securities Disclosure [Abstract]
CASH AND EQUIVALENTS AND MARKETABLE SECURITIES	CASH AND EQUIVALENTS AND MARKETABLE SECURITIES The Company considers all highly liquid, short-term debt instruments with original maturities of three months or less to be cash equivalents. Marketable debt securities consist primarily of commercial paper, medium-term corporate notes, and U.S. government and agency backed securities. The Company classifies these marketable debt securities as available-for-sale at fair value in “Marketable debt securities, at fair value.” The Company's investment in GCS Holdings is included in "Other Assets" as available-for-sale and at fair value. The Company records the amortization of premium and accretion of discounts on marketable debt securities in the results of operations. The Company uses the specific identification method as a basis for determining cost and calculating realized gains and losses with respect to marketable debt securities. The gross gains and losses realized related to sales and maturities of marketable debt securities were not material during the three months ended April 1, 2017 and the year ended December 31, 2016 . Investments in available-for-sale marketable debt securities are as follows at April 1, 2017 and December 31, 2016 : Amortized Cost Unrealized Gains Unrealized Losses Fair Value 2017 2016 2017 2016 2017 2016 2017 2016 U.S. government and agency backed securities $ 35,116,536 $ 36,343,817 $ — $ — $ (201,268 ) $ (252,556 ) $ 34,915,268 $ 36,091,261 Corporate debt and certificates of deposit 14,475,561 25,323,428 — — (33,326 ) (39,288 ) 14,442,235 25,284,140 Total $ 49,592,097 $ 61,667,245 $ — $ — $ (234,594 ) $ (291,844 ) $ 49,357,503 $ 61,375,401 The contractual maturity of the Company’s marketable debt securities is as follows at April 1, 2017 : Less than One year One to Five years Greater than Five years Total U.S. government and agency backed securities $ 15,495,380 $ 15,501,588 $ 3,918,300 $ 34,915,268 Corporate debt and certificates of deposit 13,484,735 957,500 — 14,442,235 Total $ 28,980,115 $ 16,459,088 $ 3,918,300 $ 49,357,503 The Company conducts a review of its marketable debt securities on a quarterly basis for the presence of other-than-temporary impairment (OTTI). The Company assesses whether OTTI is present when the fair value of a debt security is less than its amortized cost basis at the balance sheet date. Under these circumstances OTTI is considered to have occurred (1) if the Company intends to sell the security before recovery of its amortized cost basis; (2) if it is “more likely than not” the Company will be required to sell the security before recovery of its amortized cost basis; or (3) the present value of expected cash flows is not sufficient to recover the entire amortized cost basis. The Company further estimates the amount of OTTI resulting from a decline in the creditworthiness of the issuer (credit-related OTTI) and the amount of non credit-related OTTI. Non credit-related OTTI can be caused by such factors as market illiquidity. Credit-related OTTI is recognized in earnings while non credit-related OTTI on securities not expected to be sold is recognized in other comprehensive income (loss). The Company did not record an OTTI for the three months ended April 1, 2017 and March 26, 2016 .

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS	3 Months Ended
	Apr. 01, 2017
Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS Financial instruments are categorized as Level 1, Level 2 or Level 3 based upon the method by which their fair value is computed. An investment is categorized as Level 1 when its fair value is based on unadjusted quoted prices in active markets for identical assets that the Company has the ability to access at the measurement date. An investment is categorized as Level 2 if its fair market value is based on quoted market prices for similar assets in active markets, quoted prices for identical or similar assets in markets that are not active, based on observable inputs such as interest rates, yield curves, or derived from or corroborated by observable market data by correlation or other means. An investment is categorized as Level 3 if its fair value is based on assumptions developed by the Company about what a market participant would use in pricing the assets. The following table details the fair value measurements of the Company’s financial assets: Fair Value Measurement April 1, 2017 Using: Total Level 1 Level 2 Level 3 Cash and Equivalents $ 18,393,066 $ 18,393,066 $ — $ — U.S. Government Securities 34,915,268 6,943,660 27,971,608 — Corporate Debt 6,832,185 — 6,832,185 — Certificates of Deposit 7,610,050 — 7,610,050 — GCS Holdings 261,788 261,788 — — Warrant 274,000 — — 274,000 $ 68,286,357 $ 25,598,514 $ 42,413,843 $ 274,000 Fair Value Measurement December 31, 2016 Using: Total Level 1 Level 2 Level 3 Cash and Equivalents $ 15,822,495 $ 15,822,495 $ — $ — U.S. Government Securities 36,091,261 7,144,767 28,946,494 — Corporate Debt 7,557,029 — 7,557,029 — Certificates of Deposit 17,727,111 — 17,727,111 — GCS Holdings 331,454 331,454 — — $ 77,529,350 $ 23,298,716 $ 54,230,634 $ — The corporate debt consists of floating rate notes with a maturity that is over multiple years but has interest rates which are reset every three months based on the then-current three month London Interbank Offering Rate (three month Libor). The Company validates the fair market values of the financial instruments above by using discounted cash flow models, obtaining independent pricing of the securities or through the use of a model which incorporates the three month Libor, the credit default swap rate of the issuer and the bid and ask price spread of the same or similar investments which are traded on several markets. The Company has a warrant to acquire up to 15% of the next round of equity offered by a customer as part of the licensing of technology to the customer. The fair market value of the warrant was determined based upon expectations from the customer’s management and then applying probabilities of occurrence and discounting back the values using expected returns required for similar instruments. The carrying amounts of cash and equivalents, accounts receivable, accounts payable and accrued liabilities approximate fair value because of their short-term nature. If accrued liabilities were carried at fair value, these would be classified as Level 2 in the fair value hierarchy.

Earnings Per Share [Abstract]
Net (loss) Income per share	NET LOSS PER SHARE Basic net loss per share is computed using the weighted average number of shares of common stock outstanding during the period less any non-vested restricted shares. Diluted earnings per common share, if applicable, is calculated using weighted average shares outstanding and contingently issuable shares, less weighted average shares reacquired during the period. The net outstanding shares are adjusted for the dilutive effect of shares issuable upon the assumed conversion of the Company’s common stock equivalents, which consist of outstanding stock options and non-vested restricted stock units. The following were not included in weighted average common shares outstanding-diluted because they are anti-dilutive or performance or market conditions had not been met at the end of the period: Three Months Ended April 1, 2017 March 26, 2016 Non-vested restricted common stock 3,067,674 2,694,016

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
STOCK-BASED COMPENSATION	STOCK-BASED COMPENSATION The fair value of non-vested restricted common stock awards is generally the market value of the Company’s common stock on the date of grant. The non-vested restricted common stock awards require the employee to fulfill certain obligations, including remaining employed by the Company for one , two or four years (the vesting period) and in certain cases also require meeting either performance criteria or the Company’s stock achieving a certain price. For non-vested restricted common stock awards which solely require the recipient to remain employed with the Company, the stock compensation expense is amortized over the anticipated service period. For non-vested restricted common stock awards which require the achievement of performance criteria, the Company reviews the probability of achieving the performance goals on a periodic basis. If the Company determines that it is probable that the performance criteria will be achieved, the amount of compensation cost derived for the performance goal is amortized over the anticipated service period. If the performance criteria are not met, no compensation cost is recognized and any previously recognized compensation cost is reversed. Some of the restricted stock awards vest upon our stock price achieving certain levels. These awards are referred to as Liability Awards and are mark to marketed. Accordingly in some periods there is expense and in other periods the expense may reverse. The Company recognizes compensation costs on a straight-line basis over the requisite service period for time-vested awards. Non-Vested Restricted Common Stock Shares Weighted Balance, December 31, 2016 3,007,674 $ 3.21 Granted 60,000 3.43 Forfeited — — Vested — — Balance, April 1, 2017 3,067,674 $ 3.22 Stock-Based Compensation The following table summarizes stock-based compensation expense within each of the categories below as it relates to non-vested restricted common stock awards for the three months ended April 1, 2017 and March 26, 2016 (no tax benefits were recognized): Three Months Ended April 1, March 26, Cost of component revenues $ 104,092 $ 142,534 Research and development 218,558 116,895 Selling, general and administrative 969,455 (202,975 ) Total $ 1,292,105 $ 56,454 Unrecognized compensation expense for non-vested restricted common stock as of April 1, 2017 totaled $5.3 million and is expected to be recognized over a weighted average period of approximately three years. The Selling, general and administrative expense includes Liability Awards and the increase in expense for the three month period ended April 1, 2017 as compared to March 26, 2016 is the result of a higher stock price of the Company at April 1, 2017 as compared to March 26, 2016 . Included in Other accrued liabilities is $1.6 million in deferred compensation from equity awards which are classified as Liability Awards.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES The Company’s tax benefit of approximately $1.1 million for the three months ended April 1, 2017 represents a net benefit of $62,000 for foreign income taxes including interest income on intercompany loans, uncertain tax positions and a benefit for the net reduction in estimated foreign withholding. In addition, as a result of the acquisition of a company, we recognized $1.1 million of net deferred tax liabilities which provides evidence of recoverability of our net deferred tax assets that previously carried a full valuation allowance. We reduced the valuation allowance on our net deferred tax assets in the amount of $1.1 million and such reduction was recognized as a benefit for income taxes for the year three month period ended April 1, 2017 . The Company’s tax provision of approximately $141,000 for the three months ended March 26, 2016 , represents the net movement in estimated foreign withholding on anticipated future remitted earnings of an international subsidiary and state taxes. As of April 1, 2017 , the Company has available for tax purposes U.S. federal NOLs of approximately $141 million expiring through 2036 . The Company has recognized a full valuation allowance on its domestic and certain foreign net deferred tax assets due to the uncertainty of realization of such assets. During the three months ended April 1, 2017 we recorded $0.2 million of expense resulting from the amortization of the intangibles. Ownership changes, as defined by the Internal Revenue Code, may substantially limit the amount of net operating loss carryforwards that can be utilized annually to offset future taxable income. The ownership change in 2017 did not result in an annual net operating loss limitation as the acquired entity was an S Corporation and did not have loss carryforwards. Subsequent ownership changes could affect the limitation in future years. Such annual limitations could result in the expiration of net operating loss and tax credit carryforwards before utilization. The tax years 2001 through 2016 remain open to examination by major taxing jurisdictions to which the Company is subject to United States federal tax for the consolidated group. These periods have carryforward attributes generated in years past that may still be adjusted upon examination by the Internal Revenue Service or state tax authorities if they have or will be used in a future period. State statutes are generally shorter with shorter carryforward periods. The Company is currently not under examination by the Internal Revenue Service and is currently under examination by Massachusetts for the 2013 tax year. The Company recognizes both accrued interest and penalties related to its uncertain tax positions related to intercompany loan interest and potential transfer pricing exposure related to its Korean subsidiary. The Company has concluded that it does not maintain its permanent reinvestment assertion with regard to the unremitted earnings of its Korean subsidiaries. As such, it accrues U.S. tax for the possible future repatriation of these unremitted foreign earnings. If the Company were to repatriate these earnings, it expects to have foreign withholding at a rate of 16.5 %and does not expect any taxes to be paid in the U.S when repatriated as it currently is expected to be a return of capital.
