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.
