Abstract: A compact, economical system for magnifying a television image. A fresnel lens of focal length up to 10 inches projects an image from a television image source onto a rear projection screen. Lens aberrations and light quality are controlled by an opaque enclosure which fits around the lens, extends toward the screen, and terminates at a variable aperture. A means is provided for intercepting nearly all light from the television source that is directed toward the screen but does not pass through the lens. The system may be adjusted to be compatible with any conventional television set.
