To allow our team to spend quality time with their families this Thanksgiving, Gentex will be closed Thursday, Nov. 24, 2022 to Sunday, Nov. 27, 2022 and will not be processing any online orders. Thank you for your understanding.



Within their new 12,700 square foot, state-of-the-art, climate-controlled laboratory, Gentex utilizes their broad range of testing capabilities for characterizing the optical and mechanical properties of materials, finished components, and end-items. Failure mode and effects analysis can be supported and has been conducted in the past to examine minute defects that can occur both in anti-scratch hard coat (high power microscopy) and in vacuum deposited thin films (laser interferometer).
