QED Technologies, a wholly owned subsidiary of Cabot Microelectronics Corp., has introduced the Q-Flex, its next-generation magnetorheological finishing (MRF) optics polishing system. Q-flex offers the determinism of MRF in a newly designed modular platform that allows quick configuration changes and provides manufacturing capabilities for difficult spheres, aspheres and free-form optics. It incorporates new MRF polishing head designs with 20-, 50- and 150-mm wheels. Features such as kinematic base plates and automatic head alignment enable tool-free head changeovers in minutes. The new head design also enables polishing of more challenging optical designs. The fluid control modules make fluid changes fast, and the integrated electronic fluid management system provides greater fluid stability and continuity from day to day and from machine to machine.
