Precision rectangular windows are designed to be used in precision optical systems. Windows have high optical transmission with little distortion of the transmitted signal. We also offer anti-reflection coated precision windows for Nd:YAG laser applications.

 

If you would like to order a window with a coating of your choice, please note the code of the window and the code of the coating in your request. For required coating please refer to the COATINGS section.
