FUSED SILICA (Russian KU-1, KU-2, KV, KI, KS-4V) OPTICS Fused Silica, or Fused Quartz, is used for windows, lenses and prisms in the transmission range 0.16-3.5mkm. Fused Silica is a high purity synthetic amorphous silicon dioxide. This noncrystalline, colorless, silica glass combines a very low thermal expansion coefficient with excellent optical qualities and exceptional transmittance over a wide spectral range, especially in the ultraviolet. It is resistant to scratching and thermal shock. Alkor Technologies - Russian manufacturer of Fused silica optical components. We supply Fused Silica windows, Fused silica lenses, Fused Silica wedges, Fused Silica prisms, mirrors according to customer's specifications and drawings. Fused silica is available in UV, Visible, IR grades for different applications. Please contact us for more information. 1. KU-1 - Ultraviolet grade Fused Silica (SiO2) 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: Maximum dimensions: Dia 300x100mm  2. KV- Visible grade Fused Silica (SiO2) KV quartz glass has high transparency within visible region. It has an intensive absorption band at 170-250 and 2600-2800nm wavelength range. (Equivalent to T08, OZ) Maximum dimensions: Dia400x250 mm 
3. KI - Infrared grade Fused Silica (water free) KI features high transparency within visible and infrared regions. It has no OH-absorption bands within 2600-2800 nm wavelength interval. Maximum dimensions: Dia400x250mm 
4. KS-4V - full spectrum Fused Silica KS-4V combines excellent physical properties with outstanding optical characteristics. It has no absorption bands within 170-250 nm wavelength range as well as no OH-absorption at around 2600-2800 nm. It is practically free from bubbles and inclusions. At near IR range the nearest analogue of quartz glass KS-4V is Infrasil (Heraeus). Maximum dimensions: 260mm Diameter  |
