Summary of Significant Accounting Policies
Summary of Significant Accounting Policies	Note 2. Summary of Significant Accounting Policies Basis of Presentation - The accompanying unaudited financial statements have been prepared in accordance with U.S. generally accepted accounting principles for interim financial information and with instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all the information and footnotes required by U.S. generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments considered necessary for fair presentation of the results of operations for the periods presented have been included. The financial statements should be read in conjunction with the audited financial statements and the notes thereto for the year ended December 31, 2020. Interim results are not necessarily indicative of results for the full year. Use of Estimates - The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Revenue Recognition - The Company enters into contracts with its customers that generally represent purchase orders specifying general terms and conditions, order quantities and per unit product prices. The Company has determined that each unit of product purchased represents a separate performance obligation. The Company satisfies its performance obligations and recognizes revenue at a point in time when control of a unit of product is transferred to the customer. Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring products. For most product sales, transfer of control occurs when the products are shipped from the Company’s manufacturing facility to the customer. The cost of delivering products to the Company’s customers is recorded as a component of cost of products sold. Those costs may include the amounts paid to a third party to deliver the products. Any freight costs billed to and paid by a customer are included in revenue. The Company considers collectability of amounts due under a contract to be probable upon inception of a sale based on an evaluation of the credit worthiness of each customer. The Company sells its products typically under agreements with payment terms less than 45 days. The Company does not typically include extended payment terms or significant financing components in contracts with customers. The majority of the Company’s contracts have an obligation to transfer products within one year. Thus, the Company elects to use the practical expedient where incremental cost of obtaining a contract, such as commissions, is expensed when incurred because the amortization period for those costs is one year or less. The Company treats shipping and handling activities that occur after control of the product transfers as fulfillment activities, and therefore, does not account for shipping and handling costs as a separate performance obligation. Customer deposits are funds received in advance from customers and are recognized as revenue when the Company has transferred control of product to the customer. Product revenues are recognized upon shipment of goods as the customer has assumed the significant risks and rewards of ownership and the Company is entitled to payment at this point. Service revenues are recognized upon completion as the customer cannot realize the benefit of the service until fully completed. ​ Note 2. Summary of Significant Accounting Policies (continued) During the three months ended June 30, 2021, and 2020, revenue from the photonics market was approximately 99% and 96% of total revenue, respectively. During the six months ended June 30, 2021, and 2020, revenue from the photonics market was approximately 100% and 98% of total revenue, respectively. The balance of the revenue in these periods was from the thin film solar and thin film battery markets. The top two customers represented approximately 79% and 87% of total revenue for the six months ended June 30, 2021, and 2020, respectively. International shipments resulted in 3% and 4% of total revenue for the first six months of 2021 and 2020, respectively. Employee Retention Credit - The Company qualified for federal government assistance through Employee Retention Credit provisions of the Consolidated Appropriations Act of 2021 during the current fiscal year in the amount of $255,507 during the first quarter of 2021 and $151,701 during the second quarter of 2021. The purpose of the Employee Retention Credit is to encourage employers to keep employees on the payroll, even if they are not working during the covered period because of the coronavirus outbreak. This credit is recorded in the Statement of Operations as an offset to payroll costs in their respective expense lines. A balance of $176,252 appears as a tax receivable on the balance sheets at June 30, 2021.

Recent Accounting Pronouncements	Note 3. Recent Accounting Pronouncements In June 2016, the FASB issued ASU No. 2016-13 “Credit Losses - Measurement of Credit Losses on Financial Instruments.” ASU No. 2016-13 significantly changes how entities will measure credit losses for most financial assets, including accounts and notes receivables, by replacing today’s “incurred loss” approach with an “expected loss” model under which allowances will be recognized based on expected rather than incurred losses. ASU No. 2016-13 will become effective for us in the first quarter of 2023. We are evaluating the impact that the adoption of this update will have on our financial statements.

Common Stock and Stock Options	Note 4. Common Stock and Stock Options Stock Based Compensation cost for all stock awards is based on the grant date fair value and recognized over the required service (vesting) period. Noncash stock-based compensation expense was $8,675 and $31,182 for the three months ended June 30, 2021, and 2020, respectively. Noncash stock-based compensation expense was $30,563 and $62,362 for the six months ended June 30, 2021, and 2020, respectively. Unrecognized stock-based compensation expense was $8,669 as of June 30, 2021, and will be recognized through 2023. There was no tax benefit recorded for this compensation cost as the expense primarily relates to incentive stock options that do not qualify for a tax deduction until, and only if, a qualifying disposition occurs. The non-employee Board members received compensation of 5,265 and 51,085 aggregate shares of common stock of the Company during the six months ended June 30, 2021, and 2020, respectively. The stock had an aggregate value of $14,987 and $59,998 for the six months ended June 30, 2021, and 2020, respectively, and was recorded as noncash stock-based compensation expense in the financial statements. Employees received compensation of 4,804 aggregate shares of common stock of the Company during the six months ended June 30, 2021, which had an aggregate value of $13,211, and was recorded as noncash stock-based compensation expense in the financial statements. In addition, during the six months ended June 30, 2021, a total of 30,181 stock options were exercised by management. The cumulative status of options granted and outstanding at June 30, 2021, and December 31, 2020, as well as options which became exercisable in connection with the Company’s stock option plans is summarized as follows: Note 4.

Earnings Per Share
Earnings Per Share	Note 7. Earnings Per Share Basic income per share is calculated as income applicable to common shareholders divided by the weighted average of common shares outstanding. Diluted earnings per share is calculated as diluted income applicable to common shareholders divided by the diluted weighted average number of common shares. Diluted weighted average number of common shares gives effect to all dilutive potential common shares outstanding during the period using the treasury stock method and convertible preferred stock using the if-converted method. Diluted earnings per share exclude all diluted potential shares if their effect is anti-dilutive. All convertible preferred stock and common stock options listed in Note 4 that were out-of-the-money or anti-dilutive were excluded from diluted earnings per share. The following is provided to reconcile the earnings per share calculations: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ended June 30, ​ Six months ended June 30, ​ 2021 2020 2021 2020 Income applicable to common shares ​ $ 115,510 ​ $ 14,422 ​ $ 762,057 ​ $ 89,900 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted average common shares outstanding - basic ​ 4,497,903 ​ 4,411,714 ​ 4,488,913 ​ 4,398,856 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Effect of dilution ​ 28,159 ​ 6,611 ​ 27,565 ​ 7,622 Weighted average shares outstanding - diluted ​ 4,526,062 ​ 4,418,325 ​ 4,516,478 ​ 4,406,478 ​

After the initial six-month deferral period or until forgiveness of the loan was approved, the loan required monthly payments of principal and interest until maturity with respect to any portion of the PPP loan which was not forgiven. Under the terms of the CARES Act, PPP loan recipients are eligible to apply for, and be granted, forgiveness for all or a portion of loans granted under the PPP. Such forgiveness was subject to limitations and ongoing rulemaking by the SBA, based on the use of loan proceeds for payroll costs and mortgage interest, rent or utility costs and the maintenance of employee and compensation levels. The Company applied for forgiveness of the entire amount of the loan during the fourth quarter of 2020, and the SBA approved the Forgiveness Application in full during the first quarter of 2021. This amount is included in the Statement of Operations as gain on extinguishment of debt in the first quarter of 2021. The Company has a line of credit with Huntington National Bank for $1 million. The line of credit bears interest at 0.5 percentage points over the Prime Commercial Rate with an expiration date of October 5, 2021. At June 30, 2021, no amounts were drawn on the line of credit.

Income Taxes	Note 9. Income Taxes The provision for income taxes for the three months and six months ended June 30, 2021, is based on our projected annual effective tax rate for fiscal year 2021, adjusted for permanent differences and specific items that are required to be recognized in the period in which they are incurred. The provision for income taxes was $47,473 and $0 for the three months ended June 30, 2021, and 2020 respectively, and $138,093 and $1,900 for the six months ended June 30, 2021, and 2020 respectively. When compared to the statutory rate of 21%, the effective tax rate of 14.4% for the six months ended June 30, 2021, was due primarily to a tax benefit of $325,300 from the PPP loan forgiveness. Note 9. Income Taxes (continued) Following is the income tax expense for the three and six months ended June 30: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ended ​ Six months ended ​ ​ June 30, ​ June 30, ​ 2021 2020 2021 2020 Federal - deferred ​ $ 43,160 ​ $ — ​ $ 131,002 ​ $ — State and local ​ 4,313 ​ — ​ ​ 7,091 ​ ​ 1,900 ​ ​ $ 47,473 ​ $ — ​ $ 138,093 ​ $ 1,900 ​ Deferred tax assets and liabilities result from temporary differences in the recognition of income and expense for tax and financial reporting purposes. A valuation allowance of $0 has been recorded against the realizability of the net deferred tax asset at June 30, 2021, and December 31, 2020. The Company had net operating loss carryforwards available for federal and state tax purposes of approximately $3,700,000 at December 31, 2020, which expire in varying amounts through 2035. As of December 31, 2020, management determined that there was sufficient positive evidence to conclude that it is more likely than not that deferred taxes of $1,019,317 are realizable in part because the Company achieved four consecutive years of pretax income, expect profits to continue for the foreseeable future and implemented new efficiencies in the Company’s manufacturing process. As of each reporting date, management considers new evidence, both positive and negative, that could affect its view of the future realization of deferred tax assets. Accordingly, management determined that no valuation allowance was necessary, and the deferred tax asset was $888,315 at June 30, 2021.

The terms of the lease include monthly payments ranging from $9,200 to $9,700 with a maturity date of November 30, 2024. The Company has the option to extend the lease period for an additional five years beyond the original expiration date. There are no restrictions or covenants associated with the lease. The lease costs were approximately $55,000 and $53,900 during the six months ended June 30, 2021, and 2020, respectively.

The finance leases are structured such that ownership of the leased asset reverts to the Company at the end of the lease term. Accordingly, leased assets are depreciated using the Company’s normal depreciation methods and lives. Ownership of certain assets were transferred to the Company in accordance with the terms of the leases and these assets have been excluded from the leased asset disclosure above. During the first six months of 2021 the Company was approved by Fifth Third Equipment Finance Company for an equipment line of credit not to exceed $800,000 with an implicit rate of 2.71% at time of approval. Delivery and acceptance of new production equipment must be no later than December 31, 2021. Deposits of $319,109 were made during the first half of 2021 towards purchase orders totaling $718,900 for new equipment. The lease schedules are to commence upon acceptance of delivered equipment. The final lease rate factor or loan interest rate shall be fixed at funding using the Bloomberg SWAP Rate report for the most recent previous day close and shall remain constant throughout the term. At June 30, 2021, no amounts were drawn on the line of credit.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	6 Months Ended

Summary of Significant Accounting Policies
Basis of Presentation	Basis of Presentation - The accompanying unaudited financial statements have been prepared in accordance with U.S. generally accepted accounting principles for interim financial information and with instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all the information and footnotes required by U.S. generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments considered necessary for fair presentation of the results of operations for the periods presented have been included. The financial statements should be read in conjunction with the audited financial statements and the notes thereto for the year ended December 31, 2020. Interim results are not necessarily indicative of results for the full year.
Use of Estimates	Use of Estimates - The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Revenue Recognition	Revenue Recognition - The Company enters into contracts with its customers that generally represent purchase orders specifying general terms and conditions, order quantities and per unit product prices. The Company has determined that each unit of product purchased represents a separate performance obligation. The Company satisfies its performance obligations and recognizes revenue at a point in time when control of a unit of product is transferred to the customer. Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring products. For most product sales, transfer of control occurs when the products are shipped from the Company’s manufacturing facility to the customer. The cost of delivering products to the Company’s customers is recorded as a component of cost of products sold. Those costs may include the amounts paid to a third party to deliver the products. Any freight costs billed to and paid by a customer are included in revenue. The Company considers collectability of amounts due under a contract to be probable upon inception of a sale based on an evaluation of the credit worthiness of each customer. The Company sells its products typically under agreements with payment terms less than 45 days. The Company does not typically include extended payment terms or significant financing components in contracts with customers. The majority of the Company’s contracts have an obligation to transfer products within one year. Thus, the Company elects to use the practical expedient where incremental cost of obtaining a contract, such as commissions, is expensed when incurred because the amortization period for those costs is one year or less. The Company treats shipping and handling activities that occur after control of the product transfers as fulfillment activities, and therefore, does not account for shipping and handling costs as a separate performance obligation. Customer deposits are funds received in advance from customers and are recognized as revenue when the Company has transferred control of product to the customer. Product revenues are recognized upon shipment of goods as the customer has assumed the significant risks and rewards of ownership and the Company is entitled to payment at this point. Service revenues are recognized upon completion as the customer cannot realize the benefit of the service until fully completed. ​ Note 2. Summary of Significant Accounting Policies (continued) During the three months ended June 30, 2021, and 2020, revenue from the photonics market was approximately 99% and 96% of total revenue, respectively. During the six months ended June 30, 2021, and 2020, revenue from the photonics market was approximately 100% and 98% of total revenue, respectively. The balance of the revenue in these periods was from the thin film solar and thin film battery markets. The top two customers represented approximately 79% and 87% of total revenue for the six months ended June 30, 2021, and 2020, respectively. International shipments resulted in 3% and 4% of total revenue for the first six months of 2021 and 2020, respectively.
Employee Retention Credit	Employee Retention Credit - The Company qualified for federal government assistance through Employee Retention Credit provisions of the Consolidated Appropriations Act of 2021 during the current fiscal year in the amount of $255,507 during the first quarter of 2021 and $151,701 during the second quarter of 2021. The purpose of the Employee Retention Credit is to encourage employers to keep employees on the payroll, even if they are not working during the covered period because of the coronavirus outbreak. This credit is recorded in the Statement of Operations as an offset to payroll costs in their respective expense lines. A balance of $176,252 appears as a tax receivable on the balance sheets at June 30, 2021.
