ABSTRACT:
A fiber-optical Kohler illuminating device for microscopes in which a light-guide end surface serves as uniform increased-area source of secondary light. The light guide (10) terminates in a housing support (1) which can be removably attached to the microscope and for incident-light illumination can be placed directly on the tube-carrier arm (2) of the microscope and for transmitted-light illumination on the holder (5) of the condenser (7). The housing support contains, in series, an aperture diaphragm (13) arranged in the immediate vicinity of the light exit surface of the light guide (10), a collector (15), and an illuminating field diaphragm (16) arranged behind the collector.
