The invention relates to an optical arrangement and a method for correcting centration errors and/or angle errors in a beam path. The beam path here comprises an optical compensated system in which at least two optical elements are present and aligned relative to one another such that imaging aberrations of the optical elements are compensated. According to the invention, a correction unit is arranged in an infinity space of the beam path and between the at least two optical elements, wherein the correction unit changes the propagation direction of radiation propagating along the beam path and the correction unit either has a reflective surface or is embodied to be transmissive for the radiation. The correction unit is movable such that the angle of a change in the propagation direction can be set.

The invention relates to a method for calibrating a digital optical imaging system, comprising at least one motorized or coded zoom system and an image sensor, to a method for correcting aberrations in such an imaging system, and to an optical imaging system which is configured to carry out the methods according to the invention. During the calibration method, a reference object is recorded in various zoom settings and the image is corrected pixel-wise with digital-optical means using a previously determined model. To this end, distortion correction coefficients and image stability correction coefficients are ascertained. The real total magnification of the system is ascertained from the corrected image. The model ascertained in the calibration process also serves for correcting aberrations during operation of the imaging system.

In this telescope-type stereomicroscope, the light from an object that is being examined enters the objective. Two light bundles of the light re-exiting from the objective, which are oriented parallel to one another, enter the magnification changers. The optical axes of the magnification changers are arranged at a fixed distance from one another. Each magnification changer has an entrance pupil for the light bundle associated with it. The entrance pupil has a diameter Dthat depends on the respective selected magnification, where the condition D&#x3e;B/1.06 is met at the maximum selected magnification. Optionally, the stereomicroscope meets the condition tan(&#x3c9;)&#x2267;0.16 with respect to the angle &#x3c9; at which the light coming from an extra-axial point P at the object enters the magnification changers at the lowest possible magnification setting.
