Super Polishing Crystals
 A
large part of optical work involves the ability to produce surfaces
of exceptional smoothness. We have the capability to superpolish
many crystalline materials and achieve sub angstrom microroughness
at a flatness of < lambda/100 at 633 nm. Materials in which
we have experience include:
- Calcite
- Calcium Flouride
- Magnesium Flouride
- Magnesium Oxide
- Quartz
- Sapphire
- Silicon
If you have a special material that is not in the above list,
please feel free to contact us
and we will be happy to assist you.
