LIGHT MICROSCOPE HAVING A SAMPLE STAGE FOR CRYOMICROSCOPY

摘要

In a light microscope (1) for cryomicroscopy comprising at least one objective (2) and a sample stage (3) having a cutout (7) for a coolable holder (8) for a sample carrier mount, wherein the cutout (7) is covered by a cover (6), the sample stage (3) is displaceable in two horizontal directions (4). The cover (6) lies on the sample stage (3) in a floating fashion and the objective (2) penetrates 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 cryomicroscopy by causing liquid nitrogen to flow through a cooling line (15) open at at least one end in the holder (8) is distinguished by the fact that the quantity of liquid nitrogen is dimensioned such that the entire nitrogen is present in gaseous form at the at least one open end (16) of the cooling line (15).
