Abstract
A microtome for cutting thin sample sections utilizes an electrical contact or sole plate for guiding the section cutting knife during sectioning. The sole plate floats across the surface of the sample thereby ensuring that uniformly thin sections are cut regardless of movement of the sample or expansion or contraction thereof. An electrical contact may be used to detect and reference contact between the sample surface and the section cutting knife. After contact between the sample surface and section cutting knife is referenced, the relative position between the sample surface and section cutting knife may be adjusted to achieve a desired section thinness.
