1. A method of producing thin sections by means of a microtome comprising:
- manually driving a hand wheel (32) for producing a first thin section, anddetecting rotational movement of the hand wheel (32) during production of the first thin section with an encoder (38),determining a profile of the rotational movement, wherein the profile includes a position profile, a speed profile, an acceleration profile, a lower limit of a cutting window and/or an upper limit of a cutting window,storing the profile in a storage element (42),determining a plurality of the profiles with the encoder (38), said profiles being stored as a database in the storage element (42),storing at least one characteristic feature that is uniquely assigned to each of the profiles,selecting one of the stored profiles for producing at least a second thin section, wherein the characteristic feature of a sample is automatically determined for a sample to be microtomed, the determined characteristic feature is compared with the stored characteristic features, and one of the stored profiles is selected in dependence of the result of the comparison,and driving a motor (24) for producing the second thin section in accordance with the stored profile that is selected, wherein the motor (24) generates a cutting movement between a cutting unit (16) and a sample holder (12).

Abstract
A method of producing thin sections using a microtome is disclosed. A hand wheel (32) is manually driven for producing a first thin section, and wherein the rotational movement of the hand wheel (32) is detected by an encoder (38), and a profile of the rotational movement is determined. The determined profile is stored and selected for production of at least a second thin section. A motor (24) is driven for generating a cutting movement between a cutting unit (16) and a sample holder (12) in accordance with the respective stored profile selected for producing the second thin section. A microtome (10) to carry out this method is also disclosed.

10. A microtome for producing thin sections, comprising:
-
a sample holder (12) for receiving a sample to be microtomed, a cutting unit (16) for cutting the sample, a motor (24) for generating a relative movement between the sample holder (12) and the cutting unit (16) for cutting the sample, a manually operable hand wheel (32), an encoder (38) for detecting a rotational movement of the hand wheel (32), and a control unit (40) for driving the motor (24), characterized in that, in a recording mode, the control unit (40), using the encoder (38), determines a plurality of profiles of rotational movements (32) performed for cutting thin sections, wherein each of the profiles includes a position profile, a speed profile, an acceleration profile, a lower limit of a cutting window and/or an upper limit of a cutting window, the control unit (40) stores the profiles in a storage element (42), the control unit (40) stores for each profile at least one characteristic feature uniquely assigned thereto, and wherein the control unit (40), when producing at least one further thin section, automatically selects one of the stored profiles such that the control unit (40) determines a characteristic feature of the sample, compares the characteristic feature of the sample with the characteristic features of the profiles, automatically selects one of the profiles based on the comparison of the characteristic feature of the sample and the characteristic features of the profiles, and drives the motor (24) in accordance with the profile that is selected.
