their polarization states, are designed for engraving, marking, and scribing lasers. The beam splitters facilitate power measurements and other dual uses by reflecting a percentage of the beam, typically 50% or polarization insensitive beam, which covers all polarizations. The beam combiners permit alignment and focusing by providing a visual light beam.
