High Power Polarization Beamsplitter Cube
Two Channel Polarizing Beamsplitter Cube
Comparing to the standard Polarizing Beamsplitter cube, this Two Channel Polarizing beamsplitter cube has advantage on the extinction ratio of reflection beam. Therefore, it will be a suitable choice for many applications invloes Interometer.
Polarizing Beamsplitter Plate
Dichroic Sheet Polarizer
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.
Glan Taylor Polarizer
Glan Taylor polarizer is made of two birefringent prisms that are assembled with an aire space. The polarizer with no side escape windows is suitable for low to medium power application where the side rejected beams are not required.
Wollaston Polarizers
Wollaston polarizer is made of two birefringent material prisms that are cemented together. The deviations of the ordinary and extraordinary beams are nearly symmetrical about the input beam axis, so that the Wollaston polarizing beam splitter has approximately twice the deviation of the Rochon. The separation angle exhibits chromatic dispersion, as shown in the blow. Any separation angle can be designed upon the requirement
Glan Thompson Polarizer
Glan Thompson Polarizer Beamsplitter Cube is made of two calcite prisms cemented together. It have been arranged to permit ther output of the s-polarized beam at 45 ° from the straight through p-polarized beam. They provide high polarization purity and high transmission in the two emerging beams. These are useful if it is required to utilize both linear polarization states . They are mounted in a rectangular metal cell and surrounded with an absorbing compound.
Glan Laser Polarizer
Glan Laser prism polarizer is made of two same birefringent material prisms that are assembled with an air space. The polarizer is a modification of the Glan Taylor type and is designed to have less reflection loss at the prism junction. The polarizer with two escape windows allow the rejected beam to escape out of the polarizer, which makes it more desirable for high energy lasers. The surface quality of these faces is relatively poor as compared to that of entrance and exit faces. No scratch dig surface quality specifications are assigned to these faces.
