Polarization Beam Splitter

Polatization Beam Splitter

Polarization Beam Splitter / Combiner

Polarization beam splitter can be used as beam splitters or beam combiners. The output beam which are parallel to input beam is called p-polarized beam while the orthogonal output beam is defined as s-polarized beam.

The polarization beam splitter plates are available for red, blue and green lasers, you can choose the one you require, we will offer our customers the solution for the beam combining.

SLOC can offer complete combining laser system, with the polarization beam splitter, which makes the output power double of the single laser. The system is available for both red lasers, blue lasers and green lasers upon your request.

Instruction
1. Please aim the laser A at the surface without film like showed in the picture. The approximate angle is 20 degree. Please adjust the mirror slightly to get the best output power. Please fix the positions of laser A and mirror. 2. Please aim the laser B at the surface filmed like showed in the picture. The approximate angle is 20 degree. Please adjust the laser B slightly to mix them into one beam. If the beams aren’t in the same position, please adjust the pitching of the mirror to get the same position.
	Reflectance	Transmittance
Laser A	5%	95%
Laser B	95%	5%
