Cubic beam splitter

non-polarizingdielectric

This non polarizing beam splitter cube is coated with a broadband antireflection coating and a spectroscopic coating, which’s transmission wavelength is 400-700 nm. Its split ratio is 10:90, 30:70, 50:50, 70:30 or 90:10, and its beam deflection can be minimized after optimizing design. The beam splitter cube is composed of two prisms, the reflecting surface of a single prism can avoid ghosting. , and the inclined plane of one prism is coated with a dielectric light splitting film. Finally, two prisms are glued with photosensitive glue.
