The Polarization Beam Combiner is made of two pieces YVO4 Prism or Calcite Prism. The Calcite Polarization combiner can be with 45° or 90° of two polarization Beam Input. Please refer to Glan Thompson Beamsplitter Cube (Page 53), The Glan Thomposn Beamsplitter made of calcite can also wark as polarization Beam combiner. But since it is glue cemented, the damage threshold is lower. While we specially design the air spaced Polarization Beam combiner, which is made of YVO4. The Angle between two input polarization beam is 100.6 deg. All the input & output surfaces are optical polished and coated.
