Broadband Beamsplitter Plate

Product Description: 

A beamsplitter plate has a partially transmitting coating on one surface and an antireflection coating on the second surface. When the angle of incidence (AOI) is 45 degrees, it separates a beam into two orthogonal beams. The ratio of the power between two beams is determined by the coating. It is stated for unpolarized light. A nonpolarizing plate beamsplitter, tailored for a specific wavelength, can ensure the appropriate performance.
