Abstract
The present invention relates to an optical measuring device comprising an illumination system, a CCD camera and an image processing device for determining the dimensions of hollow or tubular miniature components, in particular stents. For this purpose the stent is slid onto an object slide and rotated in order to image it from all sides by means of the camera. The structure of the object slide is such that, before exiting, incoming light is multiply refracted by said structure, so that the object slide gives off an essentially homogeneous light, i.e. so that each surface element of the light outlet surface has essentially the same radiation intensity.
