Abstract

A microtome includes: a base element; a mid element movably connected to the base element via a joint; a first cutting apparatus element; a second cutting apparatus element; a first actuator apparatus configured to move the first cutting apparatus element relative to the mid element in a delivery direction in order thereby to set a delivery of the object to the blade; a measuring apparatus configured to measure a position of the mid element or of the first cutting apparatus element in the delivery direction relative to a reference; and a controller configured to control the first actuator apparatus on the basis of the position measured by the measuring apparatus. This can compensate the effect of the mechanical play of the joint on the first cutting apparatus element.
