摘要： An optical system for a microscope for imaging an object includes: a telescope system having an optical correction unit, which is adjustable in order to correct a spherical imaging aberration, and having a zoom optical unit, which is adjustable in order to adapt a magnification of the telescope system to a ratio of two refractive indices, one of which is assigned to an object side and an other of which is assigned to an image side, within a predetermined magnification range. The telescope system is telecentric over an entire magnification range both with respect to the object side and with respect to the image side by the zoom optical unit contained in the telescope system.

摘要： A microscope includes an optical imaging system with an adjustable corrector, a microscope drive, a position sensitive detector, an optical measuring system and a control unit. The optical measuring system configured to form first and second measuring light beams, direct the measuring light beams into an entrance pupil of the optical imaging system eccentrically with first and second distances to the optical axis thereof, receive first and second reflection light beams, and direct the reflection light beams onto the position sensitive detector. The control unit is configured to record positions of the reflection light beams on the position sensitive detector, and determine an aberration based on the recorded positions.

摘要： An optical imaging device for a microscope includes an objective and an optical system configured to interact with the objective for optically imaging an object selectively in a first operating mode and a second operating mode. The optical system includes a first optical subsystem associated with the first operating mode, and a second optical subsystem associated with the second operating mode. The first optical subsystem is configured to form a first image of the object with a first magnification. The second optical subsystem is configured to form a second image of the object with a second magnification that is less than the first magnification. The second optical subsystem includes an optical module insertable into the optical path for selecting the second operating mode. The optical module includes a lens element with a positive refractive power.
