Patent ID: 8837043

Claim:
An illumination device for medical-optical observation apparatus comprising: an illumination optical unit with a collector optical unit ( 17 , 217 ) forming an entry end for receiving light from an illumination light source, a condenser optical unit ( 19 , 219 ) forming an exit end for illuminating an observation object ( 23 ) with illumination light from the illumination light source ( 7 , 207 ) and an aperture diaphragm ( 29 , 229 ) located between the collector optical unit ( 17 , 217 ) and the condenser optical unit ( 19 , 219 ); and at least one light source arrangement ( 101 , 201 ) having at least one luminescence emitter ( 3 , 203 ) as primary light source and an imaging optical unit ( 5 , 105 , 205 ) wherein the light source arrangement ( 101 , 201 ) is located in front of the collector optical unit ( 17 , 217 ) of the illumination optical unit such that the imaging optical unit ( 5 , 105 , 205 ) of the light source arrangement ( 101 , 201 ) generates an image ( 7 , 207 ) of the at least one luminescence emitter ( 3 , 203 ) with a defined magnification scale at a distance from the aperture diaphragm ( 29 , 229 ) and between the imaging optical unit ( 5 , 105 , 205 ) of the light source arrangement ( 101 , 201 ) and the collector optical unit ( 17 , 217 ) of the illumination optical unit, and wherein the image ( 7 , 207 ) with the defined magnification scale forms the illumination light source for the illumination optical unit.
