SiLWIR™ Silicon Protective Windows are an industry first, offering a cost-effective and readily available solution – compared to germanium – for Long-Wave Infrared (LWIR) thermal imaging from 8-12µm. They feature a Diamond-Like Carbon (DLC) coating for durability and a BBAR Anti-Reflection (AR) coating to maximize transmission.
SiLWIR™ Protective Windows can withstand harsh environments and temperatures up to 200° C, are suitable for weight-sensitive applications, and adhere to MIL-F-48616 and MIL-C-48497C standards for severe abrasion resistance. With a Knoop Hardness of 1150, they’re low density, robust, lightweight and less prone to breakage.
