Polarization beamsplitter cubes are constructed by cemented two right angle prisms, the hypotenuse of one prism is coated with polarization dielectric coating.
When used with normal incident, un-polarized light, the incident beam is separated into two polarized beams, p-polarized component is passed straight through, s-polarized component is reflected out at 90deg.
