摘要： An apparatus for mounting an objective to a microscope structural member, and a method for operating a microscope. The apparatus for mounting an objective to a microscope structural member includes a receptacle, which is mounted or mountable to the microscope structural member, a slide-in part, which is mounted or mountable to the objective and is insertable into the receptacle where it can be brought into a locked position in which there is play between the slide-in part and the receptacle, and a tensioning unit, which, in the locked position, braces the slide-in part and the receptacle against each other in order to eliminate the play. The apparatus furthermore includes a first collision detection device, which has at least one first displacement sensor for detecting a displacement of the slide-in part and/or of the objective, in each case relative to the receptacle.

摘要： The invention relates to a zoom objective lens with continuously adjustable magnification, comprising five lens groups, where the first lens group, the second lens group and the fifth lens group are fixed in relation to an object. The third lens group and the fourth lens group are axially displaceable. The following conditions apply to the lens: the variable air gap between the second lens group and the third lens group decreases or has a turning point with a transition from a low to a high magnification β, the refractive power of the second, third and fifth lens groups is positive and the refractive power of the fourth lens group is negative.
