Custom High Transmission Transparent CaF2 Optical Glass Window for UV and IR Imaging

Custom High Transmission Transparent CaF2 Optical Glass Window for UV and IR Imaging

An Optical Window is an optically flat. These regular windows are applied to isolate different physical environments while allowing light pass. When selecting windows, please consider materials, transmission, scattering, parallelism and resistance to certain environment. CaF2 is widely used in laser technology, IR detector and imaging technology etc.
