The UVBS18-1 UV Beamspliter is a 50.0 mm diameter, 4.0 mm thick UV Fused Silica beamsplitter with 50/50 reflection/transmiss
ion ratio optimized for 45° angle of incidence. This beamsplitter is designed for UV applications covering spectral range from 250 nm to 450 nm, featuring low absorption and excellent thermal stability. The back surface of the beamsplitter has a wedge that is less than 5 arc minutes to reduce undesired interference effects caused by the back reflections from both surfaces of the optics.
