Abstract

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.
