Product Description
High Durability Broad Transmission Sapphire Wafer
Sapphire wafers offer exceptional durability, erosion/corrosion resistance, and high-temperature performance with a very broad transmission range, making them ideal for demanding IR optical applications.
Key Applications
- FLIR (Forward Looking Infra Red) windows for sensors and optics requiring optical clarity over broad spectral ranges
- Conventional windows and dome shapes for erosion resistance in harsh environments with salt and blowing sand
- Infrared countermeasures (IRCM) flash lamps combining high temperature performance with broad spectral transmission
