Device for reproducing the interior surface of a cavity in a workpiece

摘要

The device (2) has an optics (10) i.e. fisheye objective, staying in image transferring connection with an image detector (12) and an evaluation device (14). An illumination arrangement (16) has a light source for illuminating an imaging area of an inner surface (4) of a hollow space (6) in a workpiece (8). A light-emitting and/or light-directing component (20) i.e. light conductor, of the arrangement is arranged at a lens (22) i.e. front lens, of the optics. The light source is formed by a LED (42) with a light radiation forming element (44) for aligning light beams emitted by the LED.
