Since 1971, Dontech has engineered and manufactured optical filters, coatings and components to enhance the optical and environmental performance of electronic displays. Dontech products are integrated into display systems to enhance contrast, reduce reflections, suppress radio frequencies (e.g. EMI / RFI shielding), provide impact and chemical protection, and increase the thermal operating range of displays.
With over 40,000ft² of engineering and manufacturing facilities in Doylestown, Pennsylvania, US, Dontech has supplied its products and services to an international customer base for more than 35 years. Dontech’s facilities include more than 10,000ft² of Class 10,000 clean rooms and optical coating labs.
Optical products are sold separately or integrated for customers. Primary markets include medical, military, avionics, industrial and electronic instrumentation.

Display enhancement using optical films, coatings and components
Dontech EDS specializes in the application of optical films, coatings and components to improve the performance of electronic displays in demanding environments such as military, aerospace, medical and outdoor environments.
Dontech will integrate its optical products into electronic displays (e.g. LCDs) and bezels for its customers. Commercial off-the-shelf (COTS) displays can be customized by Dontech to improve optical performance, operating thermal range, EMI / RFI emissions / susceptibility and mechanical durability. Dontech enhanced display solutions allow the display to function properly in demanding environments, such as direct sunlight, low or high temperatures, or emergency-response medical applications.
