Fused Silica is used for windows, lenses and prisms in the transmission range 0.16-3.5�m. Fused Silica refractive index varies from 1.55 to 1.40 through the transmission range. It is resistant to scratching and thermal shock.

UV Fused Silica KU-1 has high transparency within ultraviolet and visible regions. It has no absorption bands within 170-250 nm wavelength interval. It has an intensive OH-absorption band at 2600-2800nm wavelength range. This grade does not express fluorescence as a result of UV excitation, and is characterized by optical-radiation stability. It is practically free from bubbles and inclusions. The nearest analogues of quartz glass KU-1 are: Suprasil Standard (Heraeus), Corning HPFS 7980 , Nikon NIFS-A, China JGS1. KU-1 Windows are in UV grade Fused Silica material and usable down to 170nm. UV grade Fused Silica windows are often used as vacuum viewports and sight glasses. Maximum dimensions: Dia 300x100mm. Contact us for further information.

IR Fused Silica KI features high transparency within visible and infrared regions. It has no OH-absorption bands within 2600-2800 nm wavelength interval. Extremely low bubble and inclusion content (0.3 defects/100cm3 of defects larger than 200 microns), low-OH (<50ppm OH), low cost. Infrared grade Fused Silica windows with low "OH" content can be used for applications requiring IR transmission to about 2900-3500nm. IR Fused Silica windows and mirrors made by Alkor Technologies works in European gas analyzers and gas detectors. Maximum dimensions: Dia400x250mm. Contact us for further information.
