Adjustable hybrid diffractive/refractive achromatic lens.
Bottom Line: Inserting fluid volume through a pump system into the clear aperture region alters the membrane curvature and adjusts the refractive lens' focal position.Primary chromatic aberration is remarkably reduced through the coupling of the fluidic and diffractive lenses at selected focal lengths.Potential applications include miniature color imaging systems, medical and ophthalmic devices, or any design that utilizes variable focal length achromats.

Mentions: It is known that diffractive lenses have strong chromatic aberration . We have previously reported on designing and demonstrating adjustable focus diffractive lenses using liquid crystal as the variable index medium [2,3]. In this paper, we present an adjustable liquid crystal diffractive lens and an adjustable pressure-controlled fluidic lens that in combination (Fig. 1Fig. 1
