Optical Windows

Optical windows used to protect optical systems while maintaining transmission across the required wavelength range.

Browse Optical Window Types

Browse optical window types by material, geometry and application requirements.

N-BK7 windows for visible and near-infrared optical systems requiring good transmission, stable optical quality and reliable protection.

Fused silica windows for UV, visible and near-infrared applications requiring high transmission, thermal stability and low fluorescence.

Sapphire windows for demanding optical, thermal and mechanical environments requiring high hardness, durability and broad transmission.

Round optical windows for protective covers, optical assemblies and custom optical systems, available in different materials, sizes and coatings.

Square optical windows for imaging, sensing and optical enclosure applications requiring flat protective optical surfaces.
