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.
