Polarizing Beamsplitters

Polarizing beamsplitters consist of 2 right angle prisms.  The hypotenuse of one of the right angle prisms is thin film coated and then the 2 prisms are glued together with adhesive to form a cube.  Our single wavelength polarizing beamsplitter cubes utilize N-BK7 glass and have an anti-reflection coating on all 4 optical faces and input light is split into P-polarization (transmitted) and S-polarization (Reflected at 90 degrees).
