Abstract
In a light microscope (1) for cryomicroscopy, encompassing at least an objective (2) and a sample stage (3) having a cutout (7) for a coolable holder (8) for a sample carrier mount, the cutout (7) being covered by a cover (6), the sample stage (3) is displaceable in two horizontal directions (4). The cover (6) rests floatingly on the sample stage (3), and the objective (2) passes through a cutout (12), corresponding to the objective (2), in the cover (6). The method for cooling a holder (8) for a sample carrier mount in a light microscope (1) for cryomicroscopes, by means of a flow of liquid nitrogen through a cooling conduit (15), open at at least one end, in the holder (8), is notable for the fact that the quantity of liquid nitrogen is dimensioned so that all of the nitrogen is present in gaseous form at at least one open end (16) of the cooling conduit (15).
