The usage of flat windows allows optical radiation to pass from one environment to another, without mixing other components of these environments. Considerations in selecting windows may include transmission, scattering, wavefront distortion and resistance to certain environments. The ideal window allows an optical beam to pass from one medium to the next without changing the wavelength distribution of the beam, the transmitted wavefront or scatter any of the light out of the beam. We offer windows of three different materials, from which you may choose in accordance with the properties you need: BK7 and UV grade fused silica.

 

Windows can be supplied with a coating of your choice. If you would like to order a window with coating, 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.
