Summary:Priority to German Patent Application No. 101 15 875.0, filed Mar. 30, 2001 and hereby incorporated by reference herein, is claimed. An image-recording device for a printing form (), including an array of light sources () and a downstream microoptics (), which generates a virtual intermediate image () of the light sources (), which is distinguished by the microoptics () having a downstream optical system () of a convex mirror () and of a concave mirror () having a common center of curvature, a combination of the Offner type, which produces a real image () of the virtual intermediate images (). By employing a monolithic structure () of the optical system () of a convex mirror () and of a concave mirror (), a more compact, space-saving design is able to achieved. The image-recording device according to the present invention may be utilized to special advantage for a printing form () in a plate-exposure unit or in a print unit of a printing press.
