Laser Window
Chenyu Optics manufactures custom laser windows according to operating wavelength, CW or pulsed operation, beam size, power density, angle of incidence, dimensions, surface requirements and coating specifications.
Laser Window Overview
Laser Windows are precision protective optical components manufactured from high-purity fused silica (SiO₂). The material provides excellent ultraviolet transmission, low optical absorption and stable performance across UV, visible and near-infrared wavelengths.
Chenyu Optics manufactures laser windows from fused silica, optical glass, sapphire, calcium fluoride (CaF₂) and zinc selenide (ZnSe) for UV, visible, near-infrared and infrared laser systems.
Each laser window can be customized according to laser wavelength, CW or pulsed operation, power density, incident angle, polarization, dimensions, surface requirements and coating specifications.
Related options include Laser Protective Windows, Laser Line AR Windows and Fused Silica Optical Windows. Wavelength-specific designs can be reviewed through our Optical Coating capability.
