A-Star Photonics’ Optical Windows include: CaF2, MgF2, Fused Silica(Corning 7980 or China JGS1), Borofloat glass and Sapphire.
The most advantage optical window is CaF2 window and MgF2 window. The soft and brittle character of this two materials lead very very difficult polishing, but A-Star have mastered the mature technology to stable polish them.
We are the manufacturer and supplier of optics window in China, welcome to factory inspection .
CaF2 Window (Calcium Fluoride Window) is the most advantage product from A-Star’s Plano Workshop. Fluorides are usually toxic to humans, however CaF2 is considered relatively harmless due to its extreme insolubility.
MgF2 Windows(Magnesium Fluoride) is another advantage product of A-Star Photonics. MgF2 material is very difficult to polish due to its soft, A-Star has the stable producing line for several years. We make MgF2 Windows more than 10000pcs each month.
Fused Silica is a superior optical material possesses excellent optical, chemical and physical properties with is formed by chemical combination of silicon and oxygen. Advantages of fused silica material include: good UV and IR transmission, stability
This kind of windows is made from SCHOTT N-BK7 Glass, which has transparent range from 330-2100nm. The BK7 window has good performance over visible and near IR spectrum for most application.
We can make kinds of Optical Windows from Borosilicate Glass, Borofloat, Quartz (Fused silica) and other Chinese substitution materials. This borofloat window can bear high or low temperature impact very well.
Sapphire Window Sapphire Window is made from Sapphire material at any size are available. Besides round, Sapphire windows at shape of quadrate, triangular, or other polygonal are available.
