April 1998, QED Technologies introduced the Q22, a new production-ready
MRF system that is a breakthrough for polishing and fine figuring
high precision optics (aspheres, spheres and flats). The Q22's
flexibility and simple operation make it ideally suited for
both rapid prototyping and low to medium volume production runs.
Based on the initial process invention in Belarus, and further
development at COM, QED has now refined MRF technology into
commercially available equipment for applications in optics
manufacturing and precision finishing.
Q22 is a multiple-axis, computer-controlled machine that is capable
of rapidly performing its programmed task to very high accuracy
and precision. The MRF process, which simultaneously eliminates
SSD while improving figure, has high removal rates that keep cycle
times short. The Q22 may be used to improve precision ground or
polished optics into optics having final figure accuracies of better
than l/20 p-v in a matter of minutes. The process works well on
flats, spheres, and aspheres, but its ability to polish and figure
aspheres is its greatest contribution.
optical surface ground on the OptiPro SX50 is interferometrically
and MRF polished. The first run eliminates SSD while improving
figure. The second
run demonstrates MRF capability to further improve an already
