Patent ID: 7692857

Claim:
A device for varying and adjusting transmitted illumination for a microscope, comprising: modules for darkfield illumination, brightfield illumination, and diffuse illumination; an iris diaphragm module; an illumination unit being provided which is adapted to being selectively coupled to different modules; and actuators being provided for implementing adjustments within the modules and for producing desired connections; said actuators being operated by operating elements of a control unit, wherein the adjustments within the modules and the implemented connections are detected and are stored in the control unit so as to be reproducible; wherein the iris diaphragm module is positioned in an optical beam path in connection with the module for darkfield illumination for adapting the illumination when the illumination unit is selectively coupled to the module for darkfield illumination; and wherein the iris diaphragm module is positioned in an optical beam path in connection with the module for brightfield illumination for adapting the object field when the illumination unit is selectively coupled to the module for brightfield illumination.
