Laser Beam Combiner
Beam combiners merge two beams, commonly combining processing lasers with imaging or pointing light at the work position. Selected bands transmit or reflect as specified by customers. Our 45-degree-incidence design transmits 1064nm and reflects 650nm visible light through 90 degrees to align the 1064nm beam.
