An illumination device for a light microscope with an objective, in particular for a stereo-microscope, illuminates an object plane of the light microscope. An illumination beam path of the illumination device is defined by a light source, a field diaphragm, illumination optics with at least one illumination lens, and at least one deflection element. The object plane of the microscope is obliquely illuminated with incident illumination, wherein an axis of the illumination beam path forms an angle &#x3b2; greater than 0&#xb0; with an optical axis of the objective.
