Unpolarized beamsplitter cubes are useful for natural, incoherent or unpolarized light. It is advised not to use these cubes in polarized optical systems.
The unpolarized beamsplitter cubes consist of a pair of precision right-angle prisms carefully cemented together to minimize wavefront distortion and beam skewing. The hypotenuse of one prism is coated with a multilayer beamsplitter coating tuned to the application. The four outside surfaces of the prism are anti-reflection (AR) coated with”V” type or broadband coatings to minimize surface reflection losses over the specific wavelength range.
For proper functioning, the incoming light should be one of the following:
– natural light
– circularly polarized
– 45° linearly polarized
This means that the s-polarized and p-polarized components should be roughly equal to each other in intensity. The outgoing beams are two partially polarized beams of approximately equal intensities.
