Abstract

According to the recent innovation in plastic molding technology for aspherical lenses, an unique lens system, mostly constructed by aspherical lenses has been appearing. A typical and successful example of such lens system is the projection lens for a large screen television, which is expected to become the main stream for the coming HDTV era in the near future, because of its compactness, light weight, and proper luminance level. We have been trying to find an explicit way in the aspherical optical design for this projection lens.
