Disclosed is a comparator viewing device for simultaneously viewing objects to be compared, either macroscopically or microscopically, comprising a comparator bridge member, a pair of individual optical viewing members attached to the bridge member, each of the viewing members comprising at least one objective, a binocular tube mounted on the bridge member, the binocular tube including two eyepieces and a beam splitter interposed in a beam path between the objects to be viewed and the eyepieces, and a marking device comprising a light-emitting surface for producing a luminous spot on the objects to be viewed, this marking device being located in the beam path on the side of the beam splitter opposite the objects to be viewed, whereby the same beam path serves for viewing of the objects and also for producing the luminous spot on the objects to be viewed, and the luminous spot is always produced on the location of the object which appears in the center of the field of vision. The viewing device optionally includes a phototube mounted on the bridge member for simultaneously photographing the objects to be viewed.
