Infrared windows

We design, manufacture infrared (IR) windows, IRoptical components and blanks, polished or unpolished,  coated or uncoated.

Germanium is a most commonly used material for infrared windows and lenses in night vision and thermal-imaging systems. Germanium has excellent transmission in the 2 µm - 12 µm range

Zinc Selenide (ZnSe) is the most popular material for infrared windows in high power CO2 lasers. Our CVD ZnSe grown with special grain size control technique is very stable under thermal shock

Silicon is a material of choice for infrared optical windows in a variety of applications from infrared night vision to infrared thermal imaging systems. It is commonly used as a substrate material for infrared windows in the 1.2um-8um region.

CVD ZnS is an infrared transmitting material with high performance and relatively low cost, which is often used in the 8 to 12 microns region. Its high resistance to rain erosion and high-speed dust and particulate abrasion makes it particularly suitable for exterior IR windows on aircraft frames.

Calcium Fluoride can be used in the ultraviolet, visible and infrared spectral regions. It has excellent transmission in the ultraviolet range. Calcium Fluoride is often used in spectroscopic infrared windows and lenses due to its high transmittance  from 150 nm to 9000 nm. 

Barium Fluoride windows can be used in the ultraviolet, visible and infrared spectral regions.

Sapphire is the material of choice for durable Electro-optical / Infrared windows.  It is the hardest oxide crystal with excellent transparency and thermal properties. It has excellent transmitting property across visible and mid-infrared waveband (1.5um to 6um)
