Multi-Band Sapphire EO/IR Protective Window | Aerospace Thermal Surveillance Optical Windowce

Multi-Band Sapphire EO/IR Protective Window for aerospace thermal surveillance and night vision systems

Multi-Band Sapphire EO/IR Protective Window for Thermal Surveillance

Custom UV-IR Transmissive Sapphire Protective Window for Aerospace EO/IR & Night Vision Systems

Our multi-band sapphire protective window is developed for aerospace EO/IR thermal imaging and tactical night vision surveillance equipment. Single crystal sapphire features broadband UV to infrared light transmission and excellent thermal shock resistance. It serves as the front optical protective window for airborne surveillance systems, effectively resolving lens abrasion, temperature cycle failure and optical signal attenuation under harsh airborne environments.
