Abstract

The invention relates to a system for determining the position of a test object comprising the following features: an autocollimation telescope having a beam source for emitting a beam; a beam splitter; a detector unit and an objective lens; and an optical element embodied as a focusing device, wherein the test object, the beam source and the focusing device are arranged along a common optical axis (z), and a control device for controlling the focusing device, which is designed in such a way that the beam can be focused onto a center of curvature of a first test surface of the test object with the coordinates (x1, y1) and at least onto a center of curvature of a second test surface of the test object with coordinates (x2, y2).
