Abstract
An optical system for producing an accurate image on an optical panel inlet face surface which is highly tilted relative to the image path. The optical system comprises an image source and an imaging element that creates an image from the image source. The optical system also comprises an anamorphic telescope for reducing anamorphic distortion of the image, and a final element for directing the image toward the optical panel. The anamorphic telescope reduces magnification of the image in a first direction and enlarges magnification of the image in a second direction which is perpendicular to the first direction. The anamorphic telescope includes a first lens group, a second lens group, and a third lens group. The first lens group and the second lens group form a first anamorphic telescopic system, and the second lens group and the third lens group form a second anamorphic telescopic system.
