Image-recording device for a printing form having macrooptics of the offner type

Abstract

An image-recording device for a printing form (29), including an array of light sources (12) and a downstream microoptics (14), which generates a virtual intermediate image (18) of the light sources (12), which is distinguished by the microoptics (14) having a downstream optical system (10) of a convex mirror (26) and of a concave mirror (24) having a common center of curvature, a combination of the Offner type, which produces a real image (28) of the virtual intermediate images (18). By employing a monolithic structure (40) of the optical system (10) of a convex mirror (26) and of a concave mirror (24), 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 (29) in a plate-exposure unit or in a print unit of a printing press.
