Abstract
A rod lens comprises a sleeve having two opposite ends, two correcting lenses, one at each of the opposite ends of the sleeve, and a light-transmitting fluid contained within an enclosed space defined by the sleeve and by the correcting lenses. The correcting lens at one of the opposite ends of the sleeve is non-convex. The correcting lens at the other end of the sleeve is convex. Depending upon what properties are sought, the non-convex lens may be planar or concave, and the light-transmitting fluid may exhibit optical properties of flint glass or of crown glass. If a liquid, the light-transmitting fluid may be water or a non-aqueous liquid.
