A microtome (10) for cutting thin sections comprises a sample holder (12), a cutting unit and a drive unit for producing a feed movement between the sample holder (12) and the cutting unit for setting the thickness of the sections. The drive unit includes a piezoelectric linear actuator (50) for producing the feed movement wherein the piezoelectric linear actuator comprises a stator (52) and a runner(56) connected with the stator via at least one piezoelectric element (54) e.g. piezoelectric ceramic, piezoelectric crystal. |
