Beam combiner combines two or more wavelengths of beam - one beam in transmission and the other in reflection - into one single beam. Generally ZnSe beam combiner is coated specific coatings to transmit laser beam and reflect visible light, to combine CO2 laser beams and HeNe visible diode laser alignment beams.
