Polarizing Beamsplitter Cube
These polarizing beamsplitter cubes use two complementary prisms. The output beam parallel to the input is p-polarized while the orthogonal output is s-polarized. Built from BK-7 grade A optical glass with a polarizing beamsplitter coating on the hypotenuse and AR coatings (R < 0.25% per face) on the four outer faces. Available in narrow-band and broad-band versions from 3.2 to 50.8 mm.
