Optical Window Applications

Optical windows are excellent performers in aerospace, military and commercial avionics, scientific and medical instrumentation, academics and research, as well as industrial applications.

Need help correctly specifying an optical window?

Optical windows are transparent, optically flat substrates that separate two different environments while still allowing light to pass through. They may be either parallel (used to minimize the distortion of a transmitted beam of light of a specific wavelength) or wedged (used to direct transmitted light at a specific angle and reduce back reflection) and come either uncoated or with an anti-reflective coating used to reduce reflectance and improve transmission.

To perform as expected, having a good understanding of your application (as well as specifying the correct optical characteristics) is essential to reducing costs and procuring the perfect window.

Careful consideration should be given to the following and provided when requesting an optical window.
