Abstract

The lens comprises mounting plate 1 and glass plates 2 and 3, separated by a pair of fulcrum shims 4. The space 5 between plates 2 and 3 is filled with a liquid matching the refractive index of the glass. By applying the forces 6, the plates 2 and 3 are bent about shims 4 for varying the focus point of light beam 7 passing through such plates and opening 8 in plate 1.
