Plate beamsplitters find applications in splitting or re-combining a light beam. The front surface of our beamsplitter is coated with metallic or dielectric thin film and the back surface is AR coated. The antireflection coating on the back surface minimizes unwanted secondary reflection. Holmarc offers beamsplitters in three R/ T ratios; 30/70, 50/50 and 70/30. Custom R/T ratios and sizes are also available. Though our standard plate beamsplitters are designed for visible region between 400 nm and 700 nm, we can also provide these optics for ultraviolet and Infra-red spectral regions.
