We propose an optical design for miniature 2.5x zoom fold optics with liquid elements. First, we reduce the volumetric size of the system. Second, this newly developed design significantly reduces the number of moving groups for this 2.5x miniature zoom optics (with only two moving groups compared with the four or five groups of the traditional zoom lens(More)
This article demonstrates a method of tolerance reallocation via the Taguchi method for optical zoom lens design, which is based on the indicated specifications and corresponding tolerances derived from optical simulation in order to resolve the conventional dilemmas of performance between the modulation transfer function (MTF), relative illumination (RI),(More)
