CO2 laser beam delivery optics deliver reflectivities up to 99 percent
Laser Research Optics offers CO2 beam-steering optics for use with 25- to 200-W marking, engraving, and scribing lasers. The line includes beam combiners, beam splitters, ZnSe output couplers and front mirrors, silicon and molybdenum turning mirrors, silicon and copper phase-retardation reflectors, and germanium end- and zero-phase reflectors.
Optimized for 10.6 µm, the optics are available in diameters from 0.6 to 3.0 in. with reflectivities up to 99 percent. The output couplers provide reflectivity tolerances to ±1 percent, and the phase retarders and reflectors are offered in a variety of thicknesses with different coatings.
