ZnS Window

Features
The Window is made from ZnS material, ZnS is grown by chemical vapor deposition(CVD) method. It exhibits exceptional fracture strength and hardness leading to its frequent choice for military applications or other harsh environments. It is often used in the range of 3-5um and 8-12um. MultiSpectral grade ZnS(MS) is treated after growth to eliminate microscopic  voids and efects  which  occur  in the regular grade ZnS, thus extending the usefulness of this material to the visible region.

ZnSe Window

Features
The ZnSe Window is made from ZnSe material, Zinc Selenide is the most popular material for infrared applications. It can transmit from 0.6um to 20 um. With its low absorption at IR wavelengths and visible transmission ZnSe based components including windows, output couplers, Prisms and lenses are widely used especially for high power IR laser.

Silicon Window

Features
The Silicon Window is made from Silicon material, Silicon is commonly used as substrate material for infrared reflectors and windows in the 1.5 – 8 micron region. The strong absorption band at 9 microns makes it unsuitable for CO2 laser transmission applications, but it is frequently used for laser mirrors because of its high thermal conductivity and low density. Silicon is also useful as a transmitter in the 20 micron range.

Sapphire Window

Features
The Window is made from sapphire material, which has transparent range from 180-4500nm. The refractive index is 1.755 at 1000nm. It has strong hardness. The Sapphire window is suit for scratch resistance application with better transmission over the wide range spectrum. It can be made much thinner.

CaF2 Window

Features
The CaF2 Window is made from Calcium Fluoride material, which has transparent range from 170-7800nm. The refractive index is 1.399 at 5000nm. It has little hygroscopic susceptibility and high thermal expansion coefficient. CaF2 Windows are relatively soft and somewhat hygroscopic so polishing, coating and handling are more critical than UV Fused Silica windows. In addition, The quality of a UV window can be extremely critical, it should be of high purity and polish in order not to affect the optical system. Calcium Fluoride Windows are also applicable for a wide range of spectrum. It is particularly useful for wavelength at 2980nm laser application. 

1.Useful transmission over the spectral range from 0.2 to 8.0 microns..
2.Low solubility 3.Because of its composition CaF2 window has a much longer useful life than most other materials when use in a fluorine environment. 
4.We have two grades of material of CaF2 window. One is for UV application, the other is for IR application. A wide transmission range and low solubility makes it useful for many application, including:
> Mirror substrate for UV laser systems 
> Substrate for manufacturing Windows, Lenses for UV and IR application
