A microscopy system for simultaneously observing fluorescent and non-fluorescent regions of an object, and a method for operating the microscopy system are provided. The microscopy system includes a microscopy optical unit configured to image an object plane through an observation beam path onto an image plane, an observation filter arrangeable in the observation beam path, two light sources, one being provided for exciting a fluorescent dye in the object and another being provided for visualizing non-fluorescent regions of the object, and a controller to control the light sources individually. With a suitable configuration of the observation filter, all light sources can be operated with a minimum operating current, which ensures the stability of the light. The color rendering of the non-fluorescent regions can be set by the individual settability of the light sources which can be set such that fluorescent and non-fluorescent regions appear to be approximately equally bright.

Microscopy system and method for operating a microscopy system

An illumination device for an optical viewing apparatus has a light source including a first individual light source and a second individual light source arranged in a plane. The first individual light source has a first midpoint and the second individual light source has a second midpoint. An axial direction is defined by a vector from the second midpoint to the first midpoint. An illumination optical unit defines an optical axis which is arranged perpendicularly to the plane and intersects the plane at an intersection point. The light source is imaged toward infinity by the illumination optical unit. The first individual light source has an extent along the axial direction. The midpoint is offset by an amount (&#x394;) in a positive direction along the axial direction relative to the intersection. The relationship 0.1*L&#x2266;&#x394;&#x2266;1*Lis satisfied for the offset.

Illumination device for an optical viewing apparatus

An illumination device for an optical viewing apparatus defines an illumination beam path and includes an illumination light source having mutually independently controllable individual light sources arranged in a first plane in a two-dimensional array. The illumination device defines an illumination beam path and includes illumination optics defining an optical axis. The illumination optics form a second plane conjugated with respect to the first plane. A diaphragm unit is arranged in the second plane. The diaphragm unit has a plurality of apertures and the apertures are assigned to corresponding ones of the individual light sources.
