10.6um Laser Beam Combiner Lens Diameter 20mm 25mm

eam combiner used to combine the 500-700nm visible red line with the invisible 10.6um co2 laser line to be one line , then make the laser beam visible. 
Beam Combiner Mirror is a half-mirror,it will be two (or more)wavelengths of light are synthesized into one optical path by the transmission and reflection methods. In the CO2 laser industry,mainly make laser and light visible, generally is 10.6um infrared laser and for a bunch of 500-700nm red light together.
