Abstract

Varifocal objectives for imaging systems integrating CCD sensors are useful in numerous applications, but there are no standards to design such systems. The present paper proposes a varifocal objective, suited for a 1/2” CCD camera, working at constant distance between the object plane and the image plane and providing a variable magnification within the range of (0.33…0.68). The motion laws of the mid, negative lens, respectively the last, positive lens are calculated. The optical system is diffraction limited over the entire range.
