Detailed Product Description

High Durability Sapphire Crystal Optics For Short And Long Wavelength Applications

Sapphire is used for short and long wavelength applications (UV and IR) beyond the range where conventional optics performs adequately. High temperatures and hostile environments also necessitate the use of sapphire optics.

· Illumination windows - for very high brightness illumination, sapphire windows survive the very high heat while providing the broadest spectral transmission.

· Sapphire lightguides - sapphire rods; used in high temperature thermometry beyond the range of quartz optics.

· Optical components: lenses, prisms and other laser and infrared optics are fabricated from high optical quality sapphire.
