Nanostructured Erosion Resistant Coatings for Zinc Sulfide Windows and Domes

Forward looking infrared (FLIR) systems are imaging devices that use two basic ranges of the infrared portion of the electromagnetic spectrum: 3-5 µm (MWIR) and 8-12 µm (LWIR). These systems have applications in naval vessels, helicopters, armored fighting vehicles and fixed-wing aircraft. The goal of this proposed STTR Phase I project is to apply AR and compliant, erosion-resistant coatings to multispectral zinc sulfide, using NanoSonic’s patented Electrostatic Self-Assembly method. This coating system will dramatically increase the infrared transmission of zinc sulfide (> 90%) and maintain the integrity of the substrate through strong adhesion over a useful temperature range under adverse weather conditions. BENEFITS: Delamination Resistant Coating Systems for FLIR have applications for virtually every ground-based operation including force protection, surveillance, border patrol, perimeter security and special operations. Benefits for commercial aviation systems and camera and video devices are also anticipated.
