N-BK7 Windows

Product Description: 

Optical windows are optical materials with polished surfaces that are relatively parallel. They are used to isolate different physical environments while allowing a light beam to pass.

You may refer to this page (http://www.pmoptics.com/optical_glass.html) for material properties.
