Pay vs Performance [Table Text Block] | Pay Versus Performance As required by Item 402(v) of Regulation S-K, we are providing the following information regarding the relationship between executive compensation and our financial performance for each of the last three completed calendar years. In determining the “compensation actually paid” to our NEOs, we are required to make various adjustments to amounts that have been reported in the Summary Compensation Table in previous years since the required valuation methods for this section differ from those required in the Summary Compensation Table. The table below summarizes compensation values both previously reported in our Summary Compensation Table and the adjusted values required in this section for calendar years 2020, 2021 and 2022. Year Summary (1) Compensation (1)(3) Average SCT (2) Average (2)(3) Value of Initial Net Income Adjusted Company (4) Peer Group (4) 2022 5,914,884 894,752 1,769,683 409,560 126.48 36.09 166,942 116.6 2021 4,526,501 13,102,240 1,514,852 2,755,988 193.81 81.82 26,038 104.3 2020 2,610,509 5,331,974 1,138,308 1,483,327 118.18 132.76 (8,391 ) 66.9 (1) The PEO (principal executive officer) for each year presented was identified as Dr. Miller, the Company’s CEO.

Tabular List [Table Text Block] | The Company’s most important performance measures for each of the PEO and non-PEO NEOs is discussed under the 2022 Management Bonus Plan (the “2022 Plan”) subsection of the Compensation Discussion and Analysis section of this proxy. As more fully described in this subsection, the 2022 Plan was based on the financial performance of the Company as measured by Adjusted Operating Income. This financial metric was selected because it closely aligns operating performance with earnings per share, a key driver of shareholder value. Under the 2022 Plan, 25% of each participant’s bonus was based on individual performance which, for each of the PEO and non-PEO NEOs, factored financial goals incorporating revenue, gross margin, bookings and expenses. | | | | | | | | |
