Dontech, Inc. designs and manufactures optical filters, components and precision optics used to enhance the optical performance and function of electronic displays, camera, sensor, and laser systems used in Aerospace applications. Products include glass, fused silica, ceramic and plastic substrates coated with vacuum deposited antireflective and/or conductive coatings, as well as scratch- and abrasion-resistant coatings. Optical fine wire mesh and conductive grids are produced for more demanding EMI attenuation requirements. Product testing includes environmental parameters of MIL-810F and optical performance per MIL-14806, MIL-675C and MIL-L-85762A.
Applications for Dontech products include cockpit and flight deck liquid crystal displays (LCDs) used in direct sunlight, electromagnetic interference/radio frequency interference (EMI/RFI) shielding of displays, as well as systems and optics used in night vision systems. Dontech provides optical components embedded in display systems used in military and commercial aviation and instrument panels, as well as complete display assemblies
Aerospace electronics is a key Dontech market and includes fixed wing, rotor aircraft and space-based display and precision optics systems. To meet the requirements of these demanding applications, Dontech designs and builds a variety of optical products including EMI/RFI shielding filters, transparent heater assemblies, impact resistant glass with antireflective and conductive coatings, filters for night vision compatibility, and optics such as heated laser, sensor and camera windows for visible, IR, NIR applications.
Dontech’s products are incorporated into high performance avionic computers, air traffic control systems, military GPS and radar systems, aircraft windows, targeting and sensor systems, and LED arrays for improved EMI/RFI shielding, environmental and optical performance. Our customers range from large government and commercial prime contractors, OEMs and integrators.
To meet the EMI/RFI attenuation requirements of FCC and MIL-461 (RE101 and RE102), Dontech manufactures optical filters and display assemblies with fine wire mesh or low resistance (<5 ohms/sq.) transparent conductive coatings. Additionally, we can incorporate band rejection coatings to reflect near infrared (NIR) and infrared (IR) radiation for NVIS (per MIL-3009) and transparent heaters or heat reflectors for thermal management applications.
Dontech manufactures complete enhanced and optically-bonded display assemblies with front EMI cover glass, touch screens and rear surface transparent heaters. Dontech precision optics includes substrates such as fused quartz, sapphire and zinc sulfide optics for laser and sensor applications. Dontech can apply both antireflective and dielectrically enhanced conductive coatings for NIR and IR EMI/RFI shielding and laser applications.
