Abstract
A method for the automatic and contact-free relative approach between a specimen () and a knife () of a microtome (). A first light beam bundle (') forms a detector-side zero point and a last light beam bundle (″) forms a detector-side end point of a light band (), the light band () being arranged perpendicular to the second spatial direction (Y) and in the direction thereof spaced from the knife, a zero point (X) being assigned to a reference position of the knife blade (X). The specimen () is guided through the light band () by way of a cutting movement. The position of the highest point of the specimen (X) in the first spatial direction (X) is determined from the number of shaded light beam bundles ().
