Abstract
The optical reproduction system comprises an even number (e.g., four) of reflecting surfaces for producing an image rotated 90.degree. relative to an object to be produced, on an image plane that is parallel to the plane of the object. The incoming optical axis and the outgoing optical axis rest on the same straight line.
