Description
Windows are optical glass with ground and polished faces that are
relatively parallel.They are used to isolate two physical
environments while allowing light to pass.Windows made of BK7
material have high transmission in the visible spectral region, do
not scratch easily, do not degrade under normal operating
environment and hence do not need any special precaution or
treatment. Anti-Reflective Coating will provide higher
transmission.
When selecting windows, you should consider the following:
material,transmission,scattering,wave front distortion,parallelism
and resistance to certain environment.
China Star Optics offers all types of windows made from different
materials.Special size and materials are also available upon
request.In addition, we provide a variety of single layer or
multiplayer anti-reflecting coating on optical windows.
