A microtome, in particular an ultramicrotome, having a specimen carrier 2 which can be moved relative to a knife. The specimen carrier includes a clamping aperture for holding a specimen 3. A light source is located inside the clamping aperture in the specimen carrier so that light is transmitted, from the rear of the clamping aperture, through a specimen block which is composed of a transparent material, and through the specimen. The light source may be a bulb or a mirror 21 with a remote source 21 optically connected by a fibre optic hurdle 23. <IMAGE> |
