Laser Lens
Laser Lenses are precision components designed for focusing, collimation and beam control. High-performance optical materials provide high laser transmission, low absorption, high damage threshold and accurate focusing performance.
Laser Lens Overview
Laser Lenses 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 lenses from fused silica, optical glass, calcium fluoride (CaF₂), zinc selenide (ZnSe) and zinc sulfide (ZnS) for UV, visible, near-infrared and infrared laser systems.
Each laser lens can be customized according to wavelength, CW or pulsed operation, power density, diameter, focal length, radius of curvature, surface requirements and coating specifications.
