Abstract
A microscope is disclosed having an illumination device that includes a color temperature regulating device and a color temperature measurement device. The color temperature regulating device includes a light guide and two conversion filters that are disposed on a carrier and are adjustable in a motor-driven manner. Moreover, a color temperature control device is provided, which compares the color temperature determined in the measurement device with a predetermined theoretical value and supplies a corresponding signal to the color temperature regulating device. Furthermore, a measurement or regulating device for the intensity of illumination or light intensity is provided, which compensates the change of light intensity by a motor-controllable diaphragm in the illumination beam path.
