Abstract: The invention relates to an optical viewing system and a method of aligning an eyepiece image and an image of a camera that is part of an optical viewing system, which enables both the observation of an optical image with one eye and the capturing of the optical image with the camera. The optical viewing system comprises an optical device, an eyepiece with field diaphragm, a beam splitter, and a camera with image capturing level. According to the method, an image mask is adjusted to the eyepiece image for the camera image of the camera as follows: The eyepiece is illuminated from its side facing away from the optical device, and light passes through the eyepiece to the beam splitter so that the light is partially reflected from the first semi-reflective surface to the second semi-reflective surface and from the second semi-reflective surface to the camera, resulting in the camera capturing an image of the field diaphragm of the eyepiece as a light spot on the image capturing level.

Abstract: A method for adjusting an optical system, and to an adjustment system for use in an optical system where the adjustment system comprises a predetermined reference object having known visible reference object features, a sensor system, a data evaluation module and an image processor. The data evaluation module receives captured image data and determines at least two visible reference object features of the predetermined reference object arranged in a field of view, and determines position data containing a position deviation of an image of the object to be examined or, in the case of a stereoscopic optical system, of a first and second half-image of the object to be examined. The image processor ascertains an optical distortion of the visible reference object features and sets a corresponding geometric rectification of received image data.
