Product Description

ZnS is grown by chemical vapor deposition (CVD) method. For windows,domes and lenses for thermal-imaging system.CVD ZnS, which appears orange, mainly works in Far-infrared region Multi-spectrum ZnS (M-ZnS) shows excellent optical properties across the full band of 0.4-12μm, can be used in Far-, Mid-, Near-infrared and visible regions.CVD ZnS windows, lenses and domes with size up to Ø250x16mm. For M-ZnS, the maximum size is 300x200x15mm.Physical and Optical Properties:
