Abstract

See full text

A microtome for generating thin sections of a specimen is suggested, comprising: a sectioning knife with a knife edge coming into engagement with the specimen during generation of the thin sections along a sectioning plane, an advance unit that generates at an angle to the sectioning plane between two thin sections an advance that defines the thickness of the thin section, a linear motor having a linear stator and a linear rotor, the linear motor generating a linear relative motion between the knife edge and the specimen in order to create the thin section, wherein the linear stator generates a traveling magnetic field that drives the linear rotor, and a control unit for controlling the linear motor for performing a relative back-and-forth motion along a predetermined displacement traveling path and for controlling the advance unit between two thin sections.
