Description

Window is a piece of glass with plane parallel surfaces. It is used to isolate different physical environments while allowing light to pass. The environments may vary widely in temperature, pressure, chemical composition, phase or cleanliness. When selecting the appropriate windows the optical, mechanical and thermal properties must be considered according to the intended use.

1. BK7 Window
BK7 is a borosilicate crown optical glass with high homogeneity and low bubble and inclusion content. It is good performance over visible and near IR spectrum for most application.
 
2.Fused Silica Window
Fused silica is formed by chemical combination of silicon and oxygen. Advantages of fused silica material include good UV and IR transmission, low thermal expansion, providing stability and resistance to thermal shock and high laser damage threshold.
 
3.  Sapphire Window
Sapphire is a single crystal aluminum oxide or Al2O3 and is one of the hardest materials. It has good transmission characteristics over the visible and near IR spectrum. Sapphire exhibits high mechanical strength, chemical resistance and thermal stability.
 
4.  CaF2 Window
CaF2 is a crystal, which has good transmission from **0 nm to ***0 nm. It\'s slightly soluble in water and susceptible to thermal shock. It is commonly used in IR components.
