Magnetorheological Finishing (MRF) is a deterministic lens surface finishing process which G&H uses to improve form finish of precision optical components. This technique enables us to control optical polishing with a greater degree of precision than conventional lap polishing. These complement existing polishing capabilities for surface correction when enhanced precision is required to produce complex optics.
