Abstract
An apparatus and a method of the present invention positions an optical component among several optical components, which are arranged in a receiving device. The receiving device is rotatable about an axis or movable along a direction in such a way that an optical component is positionable and the receiving device is retainable in a retention position. A coding device having first and second coders and two detectors are also provided. Either the coding device or the two detectors are associated with the receiving device and the two detectors detect the first and second coders at spatially different points. The coding device is embodied in such a way that the two detectors detect the first coder simultaneously when the receiving device is in a retention position and no more than one detector detects the second coder when the receiving device is in a region between two adjacent retention positions.
