WebThis is a flat piece of optical mirror with a coating (dichroic or dielectric) on the front face. Plate beamsplitters are usually mounted at 45⁰ to the incident beam but accept a wide range of input angles. Refraction through the optical medium means the transmitted portion is offset slightly from the input direction.
