Beam Combiner


RGB Beam Combiner



RGB beam combiners enable any two or three primary colours in the visible wavelength region to be combined. Combiners are available for either 2 or 3 wavelengths: 2 wavelength combiners combine red/green, green/blue or red/blue. 3 wavelength combiners provide full RGB operation; enabling full colour displays. CNI can offer the output power up to 30 Watts RGB laser now.

Note: Other size,  wavelength and coating are available upon request.

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 customer the solution for the beam combining.
