Overview

(1) A non-polarizing cube beamsplitter consists of two right-angle prisms. Its reflected-to-transmitted ratio is 1:1 regardless of incident polarization. Entrance and exit faces have multilayer antireflection coatings. Unlike ordinary beamsplitters, its splitting ratio does not vary with polarization. It has a narrow effective bandwidth designed for a specific wavelength, with almost no transmitted-beam displacement or ghosting. (2) A dielectric cube beamsplitter consists of two right-angle prisms, one with a multilayer dielectric partially reflective coating on its hypotenuse. It divides incident light equally into reflected and transmitted beams at a 1:1 ratio. Entrance and exit faces have multilayer antireflection coatings. Low dielectric absorption reduces incident-light loss. The splitting ratio varies with wavelength, polarization and angle of incidence. Unlike plate beamsplitters, cube beamsplitters produce almost no beam displacement or ghosting.
