Abstract
An instrument is described for the automatic measurement of lens power across the whole aperture of a varifocal lens. The apparatus is based on an electronic focimeter controlled by an external computer, which also positions the lens by two stepper motors. Methods of display of the data are discussed, and the repeatability of measurement is illustrated.
