A line of CO2 laser beam delivery optics is available from Laser Research Optics. Lenses, mirrors and beam combiners are offered with outer diameters from 1/2 to 1 1/2 in. and focal lengths ranging from 1 to 25 in. in 1/2-in. increments. They are designed for use with 25- to 200-W lasers, provide <0.2% total absorption values and have coatings that match specific phase and polarization requirements. Applications include low-power industrial marking, laser etching and soldering systems.
