MRF Polishing brings precision, determinism and repeatability to precision optics manufacturing.

  • Provides a completely deterministic process that can be characterized to very high precision.
  • Conforms to complex surfaces, providing the flexibility to polish aspheric and full freeform shapes.
  • Significantly reduces cycle times due to its high rate of removal.
  • Maintains process stability.
  • Provides an affordable, turnkey system for precision optics manufacturing that will broaden your design options and enhance your cost effectiveness.
  • Spherical Lenses, Aspheric Lenses, Prisms, Freeforms and More

QED's MRF computer-controlled polishing systems deterministically produce better, faster, and cheaper high-precision optics.
MRF systems have revolutionized the way optics are being made.

Unparalleled Accuracy and Repeatability:

  • Obtain high-precision surfaces (lambda/50)
  • Correction of transmitted wavefront (windows, phase plates, entire system correction on one surface)
  • Optical glasses, single crystals (calcium fluoride, silicon…) and ceramics
  • Square and rectangular aperture surfaces such as prisms, cylinders, and photoblank substrates
  • Mild & wild aspheres, cylinders and freeforms
  • High-aspect-ratio optics and substrates (thin film filters, etalon substrates, semiconductor wafers...).

MRF does what many people in the optics business used to consider impossible: A turnkey system able to polish precision glass aspheres with 400 microns of departure to lambda/4 in 30 minutes

MRF can make surfaces:
    1. extremely flat,
    2. extremely spherical, aspherical, cylindrical or any other mathematically defined shape, and
    3. extremely uniform in thickness (important for silicon-on-insulator semiconductor wafer applications) or optical thickness

MRF can also improve the surface integrity by:
    1. removing micro-cracks and subsurface damage,
    2. removing residual stresses, and
    3. improving glass resistance to laser damage.
