BK7,UVF3,CaF2,BaF2, Fused silica, Sapphire Wedge Windows

Windows are optical glass with ground and polished faces that are relatively parallel. They are used to isolate two physical environments while allowing light to pass.BK7 window is the most common type of window. It has good performance over visible and near infrared wavelength region. At the same time,BK7 window is ideal for applications require minimal transmitted beam deviation. It is suitable for coating AR film.
