Adaptive double-sided fluidic lens of polydimethylsiloxane membranes of matching thickness

Abstract

A fluidic lens with double-sided polydimethylsiloxane membranes of different thicknesses that complement each other to reduce spherical aberration was fabricated. It is operated with magnetic repulsion induced by the current in the voice coil. The optical power of the proposed lens was observed to be considerably higher compared to that of a typical convex glass lens. The focal lengths of rays passing through the optical axis and the edge of the lens was measured and compared with the simulation data. The spherical aberration of the proposed lens was observed to be negligibly small compared to that of a plano-convex lens. (C) 2011 Optical Society of America
