Universal modulator disk for condenser lens arrangement of lighting device for microscope, has threaded gear, tooth gear and/or friction drive for centering, adjusting and/or angle-moderate positioning optically effective elements

摘要

The disk (10) has a set of openings e.g. eyes (12), into which optically effective elements (13) are applied for different lighting types and/or contrast methods. A threaded gear, tooth gear and/or friction drive centers, adjusts, angle-moderate positions and/or aligns the optically effective elements used in the eyes, where the disk is rotatably supported on a rotational axis (11) in a condenser lens arrangement (5). The rotational axis is arranged outside of and parallel to an optical-axis (4) of an illumination beam path.
