Product Name: Excimer-Grade Baf2 Laser Windows Model NO.: D5~D300mm Coating: Ar Bbar Customized: Customized Certification: RoHS, ISO9001, CE Lenses Color: Clear Material: Optical Glass Shape: Flats Transmittance: >95% Type: Flat Lens Usage: Optical Trademark: ICC Origin: Qinhuangdao, China HS Code: 9001909090 Product Description Barium Fluoride - BaF2Barium Fluoride is grown by vacuum Stockbarger technique in diameters up to 240 mm. The material is susceptible to thermal shock. It is transparent in the wide spectrum band. Available in both optical and scintillator grades. The scintillator grade material has typical absorbance of 0.2 at 190 nm (transmissivity of 0.013mm-1) through a 60 mm path length, and 0.08 at 300 nm (transmissivity of 0.015mm-1) Applications include windows, lenses of special types of objectives, mirror substrate in optical systems operating in UV and IR spectrum band. Diameters up to 240 mm for transmission to 12.5 um.3.Product show4.
