Abstract

The 2013 China lens design competition was to design a conjugate zoom lens with maximum magnification ratio, numerical aperture and field of view, and with specified image quality and distortion. The lens is used at visible spectrum range from 486nm to 656 nm. The goal of the problem is to maximize the product of the semi-image height, objective numerical aperture of configuration 1, image numerical aperture of configuration 2 and the magnification ratio of two configurations while holding the distortion to within ±1% and the RMS wavefront error to ≤ 0.1 wavelength within the field of view. Over 20 entries were received and the results were analyzed.
