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 ().

Optical observation unit and method for ensuring an unchanging illumination intensity when changing the color temperature of the illumination

A stand for movable equipment has a first stand part and a second stand part that is movable relative to the first stand part and includes a pivot arm hinged to the first stand part and pivotable around a pivot axis. An energy storer provides weight equalization. The energy storer exerts a force on the pivot arm, by means of a deflecting element that is directed towards an abutment point on the first stand part. The pivot axis and the abutment point always define a vertical plane. The deflecting element is arranged on the second stand part.
