Abstract

A newly designed non-telecentric projection lens is proposed for a mini-projector with LED light sources. It consists of six spherical lenses. The zoom ratio Is 1.1, and the throw ratio could operate at 1.23. Using this non-telecentric projection zoom lens, a very sharp image could be achieved with low cost.
