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(More)
This study presents a liquid lens using electrowetting that employs an oil phase floating in between the conducting fluids. The lens shape has double-sided surfaces and operates with a bias of 0-60 V. The focal length of the lens, with an aperture size of 2 mm, is ~5.8 mm, and it is converted into an optical power of 172. The lens is sufficient to suppress(More)
