An ultramicrotome is a high precision tool for cutting or polishing 60-100 nanometer surfaces. The sample block is first trimmed to create a face 1 millimeter by 1 millimeter in size. Faces usually have a square, trapezoidal, rectangular or triangular shape. Finally, thin sections are cut with a diamond or glass knife using an ultramicrotome to create a perfectly smooth surface.
