Abstract
In an illumination incoupling system for an optical viewing device, illumination incoupling is provided simultaneously into main observer beam paths and assistant observer beam paths using two semitransparent and two fully reflective deflection elements arranged crosswise and symmetrically with respect to the optical axis of the main objective. Homogeneous illumination of the specimen field may thereby be achieved for both the main observer and the assistant observer.
