A microscope (10) includes an objective system (30) and a zoom system (32). The microscope (10) furthermore has a manually rotatable rotary wheel (108) for adjusting the magnification of the zoom system (32), the rotary wheel (108) being rotatable within a predetermined maximum rotation range. The rotary wheel (108) includes a first engagement element (162, 164). In addition, at least one second engagement element (130 to 136) is movably mounted on a housing (100) of the microscope (10). This second engagement element (130 to 136) is movable between a deactivated and an activated position, being in engagement with the first engagement element (162, 164) in an activated position. The position of the second engagement element (130 to 136) is determined by the respective objective (44, 52) currently received in the beam path. |

1. A microscope (10) comprising:
an objective system (30) including at least two objectives (44, 52) selectably introducible into a beam path and having different focal lengths, and a receiving region (102) for receiving the objective (44, 52) introduced into the beam path; a zoom system (32) having a total zoom range (90), the zoom system (32) being adjustable to a selected zoom magnification within the total zoom range (90); a respective total magnification of an object to be examined microscopically being obtained respectively from the focal length of the selected objective (44, 52) and the selected zoom magnification of the zoom system (32); and a manually rotatable rotary wheel (108) for adjusting the zoom magnification of the zoom system (32), the rotary wheel (108) being rotatable relative to a nonrotatable housing (100) of the microscope within a predetermined maximum rotation range, and the total zoom range (90) being defined by the maximum rotation range, the rotary wheel (108) including a first engagement element (162, 164), at least one second engagement element (130 to 136, 142 to 148) being movably mounted on the housing (100), the second engagement element (130 to 136, 142 to 148) in a deactivated position not being in engagement with the first engagement element (162, 164) and in an activated position being in engagement with the first engagement element (162, 164), the engagement limiting the rotatability of the rotary wheel (108) to a partial rotation range that is a partial range of the maximum rotation range, and a position of the second engagement element (130 to 136, 142 to 148) being determined by the respective objective (44, 52) currently received in the receiving region (102). |
