Need help correctly specifying an optical window?

Optical windows are transparent, optically flat substrates used to 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.

For an optical window 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.
