title: Wide-converter lens design for a pico projector.
abstract: In this paper, we propose a concept for the design of a 0.702× wide-converter lens for a 0.3 in. digital micromirror device. This 0.702× wide-converter lens is capable of enlarging the size of the original projected image at the same projection distance. This 0.702× wide-converter lens is attached in front of the projection lens of a pico projector (PP). Compared with the projection lens of a PP without the 0.702× wide-converter lens, there is an increase in the size of the original projected image of 42.4% at the same projection distance. In other words, there is a saving of projection distance of 29.78% to obtain a projected image of the same size.
