Reflective Phase Retarders

Transform linear to circular polarization with our single reflective component to cut metals with narrower and more consistent kerf using high-power COlasers.

Our reflective phase retarders integrate the functionality of a quarter-wave retarder and a mirror to convert a linear polarized laser beam to circular polarization. This provides easy access to the well-established benefits of cutting with circularly polarized light.

Product Selection

Choose from silicon optics for moderate power applications and copper RPRs for high-power operation, plus a large selection of part diameters.
