Sapphire windows are suitable for applications in the IR band and is often used as a IR viewport window for thermography. We provide a large variety of Sapphire windows for vacuum viewports.
Sensors and Detectors
Sapphire UV and IR transmission properties in combination with ability to withstand harsh chemicals, high pressures and temperatures offer strong advantages for Fire and IR Detectors, protective windows for remote sensors and optics for harsh environments such oil well drilling, chemical processing and other industrial processes.
Any other shape and size are also available:
