The microscope, and especially a stereo microscope, has at least one lens system (3a,3b) for one or more eyepieces (11a,11b), and an arrangement of lenses/mirrors/prisms to give a light path (S) between the lens and eyepiece within a tube (14). The tube has at least one section to give a variable length along the line of the light path, between the lens(es) and the eyepiece(s), in a telescopic action. A group of correction lenses (15a,15b,16a,16b) can be swung in and out of the light path by a gearing, according to the length setting of the tube. |
