A dual stereoviewing operating microscope includes a single objective lens (26), which provides a single collimated beam of light, and first and second means for intercepting the collimated beam. The first and second means include first and second pairs of zoom tubes, each pair independent of the other. The microscope further includes means for intercepting the collimated beam to cause a fifth observing light path which also includes a zoom tube. |
