Gentex develops, manufactures and markets proprietary electro-optical products - products that employ sophisticated optical sensing devices and related electronic circuitry. We're also a world leader in the field of electrochromics, the science of reversibly darkening materials by applying electricity. We continue to develop new solution-phase, organic electrochromic materials that variably darken to control the transmission of light through glass.

Gentex's research lab and test center is home to a host of research scientists, chemists, electrical and mechanical engineers and others charged with continually improving the function, quality and performance of our electro-optical products. The result is a growing list of core competencies that ensure Gentex products will add value to people's lives today and well into the future.
