ABSTRACT:
A lens system that utilize a high refractive index enveloping medium in which one or more lens elements of low refractive index material are interspersed within the fluid is disclosed. Preferably, the enveloping medium is a liquid optical fluid contained in a hollow shell. Hollow air-filled chambers, fabricated from a material similar in refractive index as that of the fluid, are supported in the liquid and serve as low index refractive elements in the higher index enveloping medium.
