PCB and Waveplate Assembly

 
Polarizing Cube Beamsplitters(PCB) and waveplate assembly refers to the polarization state of S&P two polarization states of the laser beam as one. The 45° half-wave plate first converts the S-polarization state of the laser into P-polarization state, and then combines the two vertical beams of S&P polarization state into a circular polarized light through the polarization splitting prism.
 
Technology and Advantages：
Optical Contacted Design Increases Damage Threshold and Eliminates Cement Fluorescence
Greater than 98% Transmission of P-Polarized Light
High Extinction Ratio of Greater than 1000:1 
 
Application: This kind of assembly is often used in laser beam combinatory, isolator.
