PRECISION RECTANGULAR WINDOWS
Manufactured from UV grade fused silica
Precision polished on both surfaces (20-10 scratch & dig)
Parallelism up to 30 arcsec
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.
