Aluminum Variable Radius Mirrors

II-VI introduces new, light-weight aluminum variable radius mirrors (VRMs) for high-power industrial lasers. At as low as 18 % of the weight of comparable copper versions, the aluminum VRM line provides OEMs with faster cutting/welding head movement and increased cyclic lifetime. With low-roughness, polished surfaces available in custom designs for use in 1 μm applications, II-VI’s aluminum VRMs can accommodate applications up to 20 kW of laser power.
