Abstract

Traditional zoom lens designs employ multiple moving lens elements to provide simultaneous control of focal length and focal plane. We present an approach to a design of a simplified zoom lens by employing a single moving element to control only the focal length. We show that the defocus in miniaturized zoom lenses with a single moving element can be corrected by the use of wavefront coding, although this introduces a modest reduction in signal-noise-ratio. As an example, we present a design of a miniaturized 10 mm long wavefront coded 2.3x optical zoom lens with a single moving lens element.
