4Lasers polarizing cubes are beam splitters whose basis of separation is based on light polarization. S-polarized light is reflected at 90° angle and p-polarized light is transmitted with minor beam deviation (<3 arcmin), therefore they are often used for optical isolation, continuosly variable beamsplitting or just for beam separation/combining by polarization.

Polarizing cubes are made of two identical right-angle prisms with their hypotenuse faces adhered together via optical contact or epoxy glue. Epoxy glued cubes are designed for low- and medium-power applications, while optically contacted cubes – for high-power applications. Since the basis of separation is light polarization, prior to cementing a dielectric beam splitting coating is deposited onto one of the prisms hypotenuse face. In order to reduce reflection losses and ghost reflections, antireflection coatings are deposited onto the input and output faces of the right-angle prisms. It is recommended to use these elements with collimated or nearly collimated laser beams in order to avoid beam aberrations.
