We have developed a new front projector with a super‐short projection distance of 0.65 m at 100″. We installed a newly developed reflective‐type projection optical system in this projector, which was composed of only four aspheric mirrors that were free of color aberrations. Using this new system and a single‐chip DMD™*, we projected a picture that had excellent sharpness and high contrast from 40″–100″. This paper describes the principles, design, and characteristics of the new WT600™ front projector.
