Achieves Severe Abrasion Requirements of MIL-C-675C
Low Reflection Coatings for 400 - 1100nm or 2000 - 5000nm
Ideal for Harsh Environments Requiring Thin Optics
Uncoated Sapphire Windows are Also Available

High Durability Anti-Reflection (AR) Coated Sapphire Windows are designed for applications requiring the ruggedness of sapphire with AR coatings designed to survive severe abrasion. The AR coatings on these sapphire windows are designed to withstand temperature cycling from -80 to +160°F, salt spray for a continuous period of 24 hours, and salt solubility for an immersion period of 24 hours. Coating designs achieving the severe abrasion requirements of MIL-C-675C for VIS-NIR and MWIR applications are available, making them ideal for use in harsh environments. High Durability Anti-Reflection (AR) Coated Sapphire Windows are used in aerospace, defense, and industrial applications, as well as any optical application requiring thin, durable protective windows.
