ABSTRACT:
An aplanatic image combiner. At least two image generating cathode ray tubes are provided having curved concave phosphor image generating surfaces. A set of dichroic mirrors are provided to combine images from each of the curved surfaces into a single combined image. A lens is positioned to transmit the combined image to an image magnification system. The lens has a curved surface forming an exit aperture for the image combiner. The radius of curvature of the lens is configured to be substantially the same as the radius of curvature of each of the concave image generating surfaces of the cathode ray tube. An image is generated to an image magnification system without generating any field aberration or astigmatic and chromatic aberration requiring correction in the magnification system.
