Optical Windows
Commercial Grade Optical Windows
Click here for precision grade windows.
Optical windows are available in two grades (precision and commercial) to meet various specific applications. Our double sided optical flats may also be used as windows and further information can be found on our optical flats page. We also offer commercial grade windows which offer a low-cost alternative to ultra-high precision optics. They are flat to approximately one wave per inch. Other sizes are available in addition to the standard sizes listed.
