The cube beam splitter is a beam splitter commonly used in life sciences or laser applications. The function of the cube beam splitter includes an element that splits the incident light into two different lights. The cube beam splitter is a durable and easy to install beam splitter, and it has the same optical path length.

The polarization beam splitter prism can split the incident unpolarized light into two vertical linearly polarized lights. Among them, the P polarized light passes completely, while the S polarized light is reflected at an angle of 45 degrees, and the exit direction is at an angle of 90 degrees to the P light. The polarization beam splitter prism is formed by gluing a pair of high-precision right-angle prisms, and a polarizing beam splitter dielectric film is coated on the oblique side of one of the prisms.
