Patent ID: 7271966

Claim:
A microscope objective comprising: axially adjustable correction mounts for adapting to different parameters influencing the imaging quality, wherein the axial adjustment of the correction mounts relative to a stationary barrel is realized by an adjusting ring; said adjusting ring being arranged on the outer side of the barrel by a pin which is arranged in the respective correction mount, is directed radial to the optical axis of the objective and engages in through-openings of threaded rings; spring elements being provided for moving the parts relative to one another without play; wherein the objective comprises correction mounts, characterized in that the correction mounts are adjustable by at least one adjustment ring without any additional rotation around the optical axis of the objective, a barrel which is fixedly connected to an inner cylindrical sleeve with axially oriented through-openings, axially adjustable correction mounts for receiving optical elements which are mounted in the cylindrical sleeve, and a radially directed bolt or screw projecting through an associated through-opening of the cylindrical sleeve is arranged at the outer side of the correction mounts, respectively, wherein threaded rings are in an operative connection with a respective bolt, are provided with an external thread having the same or different pitch, are mounted on the cylindrical sleeve so as to be axially displaceable only, and engage in an internal thread of corresponding pitch of respective driver rings which are associated with the threaded rings and which are arranged in the barrel so as to be rotatable around the optical axis and are in an operative connection with at least one adjusting ring arranged on the outer side of the barrel and can be rotated with this at least one adjusting ring.
