Zoom lens design for video projector

摘要

Abstract: Hughes ELCAN has developed a family of video projector zoom lenses. These lenses cover a large range of optical parameters, i.e. zoom ratio, F number, projection distance, LCD size. Most configurations use only two moving groups, accomplishing zoom, compensation, and focus functions. This particular architecture allows the design of a well corrected compact zoom lens. This paper presents the procedures for initial design, using the paraxial optics equations, and the final system design using the Code V.!5
