BK7 Window

The function of the BK7 window is to transmit light radiation between two different environments, while preventing interference from other environmental substances. The window does not change the wavelength distribution of the light, the wavefront characteristics of the transmission, and does not cause the scattering of the light. The BK7 window produced by CRYLIGHT Optoelectronics has the advantages of low deformation, low scattering and high parallelism.At the same time,our engineers will help you with a special coating design.
