Abstract
A microscope objective having a plurality of lens assembly holders, one of which is designed as a correction holder (F4) for matching to different cover slip thicknesses and can be moved axially along the optical axis of the objective for position changing between lens assembly holders which are stationary relative to the objective. A cam ring (6) is arranged within the holder support (1) such that it can rotate. The correction holder (F4) is supported by means of a ball (11) or a bolt (24) on its cam (7). A pin (14), which can move radially in a holder support, is firmly connected at its one end to the cam ring (6), and its other end extends into a knurled ring (16). Turning the cam ring (6) by means of the knurled ring (16) changes the support point between the correction holder (F4) and the cam (7) of the cam ring (6), resulting in the correction holder (F4) being moved exclusively in the axial direction.
