II-VI Incorporated announced the introduction of its water-cooled, aluminum variable radius mirror (VRM) for next-generation lasers with up to 20 kW output power. Next-generation laser processing heads that are rated for tens of kilowatts of power while maintaining their precision, versatility, and speed are driving the demand for laser optics that can handle higher powers while remaining lightweight. II-VI’s new VRM is water-cooled to enable laser processing heads to achieve a power rating of 20 kW and above. The VRM is made of aluminum, which is 80% lighter than comparable copper and stainless steel solutions. VRMs enable laser processing heads to precisely maintain the focal point of the laser beam on the work piece by adjusting the mirror’s radius of curvature. II-VI’s broad portfolio of laser optics is one of the largest and most advanced in the industry, leveraging deep expertise in diamond turning technology, magnetorheological finishing, and IBS coatings. II-VI also offers turnkey capabilities in optical design, fabrication, thin-film coatings, and metrology.
