• Optical material: sapphire;
• Effective aperture：90%

       Sapphire features a high surface hardness and can only be scratched by a few substances. In addition, sapphire is chemically very stable and is insoluble in water, common acids, and bases even at temperatures up to 1000°C. The transmittance range of sapphire windows covers the ultraviolet band to the mid-infrared band, and has a high transmittance in the whole wavelength range. OMTOOLS offers windows made of different materials to meet various commercial and scientific applications.
