High contrast dichroic sheet polarizer is made of dichroic film sandwiched by two glass plates. When a natural beam transmits through the dichroic material, one of the orthogonal polarization component of the beam is strongly absorbed and the other goes out with a weak absorption. So, dichroic sheet polarizer can be used to convert randomly polarized beam into linearly polarized beam. Compared with polarizing prisms, dichroic sheet polarizer offers a much bigger size and acceptable angle, but it can not be used in high power applications.
