ABSTRACT:
The invention is directed to a microscope objective with axially adjustable correction mounts and is applicable in connection with different cover slips and/or different immersion liquids and/or at different work temperatures. In the microscope objective according to the invention, helical springs which are uniformly distributed along the circumference and act in axial direction are fixed by a first ring which has pins in axial direction on which the helical springs are arranged. The pins engage in bore holes of a second ring. The bore holes are at least deep enough to ensure the required spring path. The two rings with the helical springs arranged therebetween on the pins form a spring retainer which ensures a movement of the parts without play and/or in a springing manner. In principle, the proposed solution can be substituted for all pressure springs in microscope objectives and other objectives and can overcome the disadvantages of using individual springs.
