<p>A microtome (10) comprising a sample holder (12) a cutting unit (16) and a drive unit (22) capable of producing a relative movement between the sample holder (12) and the cutting unit (16) for cutting the sample. In addition, the microtome (10) has a handwheel (32) and an encoder. A control unit (40) controls the drive unit (22) as a function of the rotational movement of the handhweel (32) detected by the encoder so that, in a first operating mode, the relative movement produced between the sample holder (12) and the cutting element (16) by the drive unit (22) when the handwheel (32) is rotated through a full revolution has a maximum first stroke length and that, in a second operating mode, the relative movement has a preset second stroke length shorter than the maximum first stroke length.</p> |
