Abstract
A device for imaging an inner surface of a cavity in a workpiece includes optics with a panoramic view, and has an image transmission connection with an image sensor and a downstream evaluation device. The device also has an illumination system with a light source for illuminating an imaging region of the inner surface imaged by the optics. Further, at least one light-emitting and/or light-deflecting component of the illumination system is provided on a lens, such as in particular a front lens, of the optics.
