An optical observation unit () has an illumination apparatus () for illuminating an observation object (). The illumination apparatus () has a light source () emitting illumination light with a first color temperature, and a spectral filter () that can be inserted in the illumination beam path. The spectral filter () converts the illumination light with the first color temperature into illumination light with a second color temperature. The illumination apparatus further has an attenuator () that can be inserted in the illumination beam path in place of the spectral filter () and has a transmission characteristic that leads to an intensity reduction of the illumination light with the first color temperature that corresponds to the intensity reduction of the illumination light with the second color temperature by way of the spectral filter ().
