ABSTRACT:
A surgical microscope (100) is especially suited for use in neurosurgery. The surgical microscope has an illuminating arrangement (101) for making available illuminating light in an operating region (117) to be examined with the surgical microscope (100). The illuminating arrangement (101) contains a high-power light source (102) which includes an intensity adjusting device (112). The intensity adjusting device (112) makes possible to adjust the intensity of the illuminating light (116), which is guided to the object region (117), between a maximum value and a minimum value. The surgical microscope (100) has a control unit (170) for the illuminating arrangement (101) which includes an operator-controlled module (172) via which the illuminating arrangement (101) can be activated and controlled. For adjusting the intensity of the illuminating light (116) guided to the operating region (117), the control unit coacts with the adjustable filter unit (112). A signal generator (175) is provided which outputs a warning signal when an intensity of the illuminating light is adjusted via the operator-controlled module (172) which exceeds the safety limit value stored in a memory (171).
