Polarizer NLO Crystals Waveplate High Power Polarization Beamsplitter EO Q-Switch

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. 

 

Features:
●Widest Field Angle
●Cemented, Suitable for low power application
●High Polarization Purity
