Custom Optical Window
Custom Optical Windows are precision components designed and manufactured according to specific optical system requirements. Suitable material, dimensions, surface specifications and coatings provide excellent transmission, surface quality and mechanical stability.
Custom Optical Window Overview
Custom Optical 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 offers optical glass, fused silica, sapphire, calcium fluoride (CaF₂), zinc sulfide (ZnS), zinc selenide (ZnSe), silicon and germanium windows for UV, visible, NIR, MWIR and LWIR applications.
Each optical window can be customized according to customer drawings, including material, shape, size, thickness, surface flatness, surface quality and AR coating.
