Abstract
A non-polarizing beam splitter can be a rectangular cuboid. A diagonal surface in the beam splitter extends from a corner between the first surface and the second surface at a 45° angle to a point on the third surface or the fourth surface. A beam of light is split into a transmitted beam and a reflected beam using the non-polarizing beam splitter.
