Product Description
Windows are optical glass with polished faces that are relatively parallel. They are used to protect laser output. Always windows are AR coated to eliminate reflection, so AR coated windows offer improved transmission when used in industrial displays or computer monitors. Their high transmission makes them ideal for most industrial and laser protecting applications. Union Optic offers all types of windows made of different materials. Special size and materials are also available upon request. In addition, we provide various coating on optical windows. |

We can supply different windows made from below materials.

Calcium Fluoride ( CaF2 ) windows can be used for Ultraviolet (UV) through to Infrared (IR) applications, due to its transmission range from 160nm up to 8 microns.
Calcium Fluoride offers Low Absorption and High Transmission. UV Grade Calcium Fluoride can be used down to 160n
IR grade can be used for Applications Ranging from 250nm through to 8μm
Calcium fluoride's low refractive index allows it to be used without an anti-reflective coating.
Windows manufactured from vacuum UV grade calcium fluoride are commonly found in cryogenically cooled thermal imaging systems.
We manufacture CaF2 windows in a wide variety of sizes, and can easily produce to your exact dimensions.
