Description
General Introduction: Raytek UV fused Silica Plano-Concave lens can be coated with multilayer antireflective film or without coating. All lenses are guaranteed λ/ 8 surface accuracy and 20-10 scratch-dig surface quality. UV fused silica is a highly pure synthetic amorphous silica, which can provide transmittance of 195-2100nm. This amorphous colorless quartz glass combines very low thermal expansion coefficient, good optical quality and excellent transmittance in the ultraviolet band. Moreover, it does not emit fluorescence under ultraviolet light and is radiation resistant.
