These are precision grade plate beam splitters. Both faces of these precision beamsplitters are polished to a high degree of flatness of ? wave and have excellent surface quality. They are made from high quality optically polished BK7 with both surfaces controlled to a high degree of parallelism. Our stock range of precision beamsplitters are available for use in Visible and Infrared wavelengths with 50/50 split ratio. The non splitting face of the beamsplitter is multilayer antireflective coated to eliminate second face ghosting effects. Typical uses for beamsplitters are in laser applications.
