ULTRATHIN DIAMOND KNIVES
The edges of our diamond knives have been shown to have a radii of curvature of 20 Angstroms or less, the sharpest edge that has ever been put on any material. Flaws in the facets that form this edge give unacceptable results, so great effort is made to achieve facets that are smooth on an atomic scale.
| Angles | Edge | Length | Thickness |
| Routine Sectioning | 45° | from 1.0-6.0mm | 30-200nm |
| EELS (special request) | 45° | from 2.0 - 4.0mm | 10-30nm |
| Soft biological | 35° | 1.0-6.0mm | 30-200nm |
| Hard material samples | 55° | 1.0-6.0mm | 30-200nm |
