Plane Windows

Here, we have a selection of plane optical windows that are optically flat and transparent.  They are used to isolate two different environments while allowing the light pass through with intended for transmissive use and are parallel to better than 3 arc minutes.  These plane optical windows perform in military, aerospace, and commercial avionics, medical instrumentation to science, research and academics, as well as industrial applications.

We offer a wide range of optical windows made from substrates like N-BK7, UV Fused Silica, Germanium, Zinc Selenide, Calcium Fluoride, and Magnesium Fluoride.  Parallel and wedged windows are available with laser grade surface quality and flatness.

If you can’t find what you are looking for, please contact one of our engineers using our contact form or call us.  We’ll be ready to assist you.
