Abstract
Light is passed through a negative located in a primary optical path and towards a band of copy material disposed in the path. A reflector is movable into the primary path so as to deflect the light into a secondary optical path. A mat, transparent plate is situated in the secondary path. The plate is situated in a plane which is a conjugate of the plane of the copy material with reference to the reflector when the latter is in the primary path. A sharp image of the negative is formed on the plate. Light passing through the plate is deflected into a tertiary optical path by a second reflector. The light entering the tertiary path is sensed by a video camera which then causes the image on the plate to be reproduced on a monitor for evaluation prior to copying.
