General Optics
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 CO2 lasers.
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.
