We are the manufacturer and supplier of optics window in China, welcome to factory inspection .
Optical Windows Available from Astar photonics inc.
Our state of the art factory is able to manufacture both large optical windows. A wide variety of optical substrates are available to choose from, and since production is carried on in-house our design team will be able to match your exact specifications when carrying out your order.
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.
Optical windows are flat plates made of optically transparent material, designed to allow light into an optical instrument. They can also be used to protect a light source from an outside environment.
These windows are designed to minimize both reflection and absorption while maximizing transmission over a target wavelength range. When choosing an optical window, you will have to keep in mind optical surface specifications, material transmission properties, and the mechanical properties required by your application.
BK7 Window
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.
Borofloat Windows
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 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.
