Adjustable Hybrid Diffractive/Refractive Achromatic Lens

Researchers at the University of Arizona have designed an achromatic variable focus lens that can correct for Seidel Aberrations in addition to chromatic dispersion. The technology uses fluid pressure control to alter the curvature of clear membranes containing fluid in correlation with the wavelength and the desired focal length. Software enables the...

Non-Mechanical Auto-Focus and Optical Zoom

A design for a non-mechanical zoom system using variable focus elements without moving parts to create optically zoomed images has been developed by researchers at the University of Arizona. Three different magnifications have been demonstrated, and unlike digital zoom, enhanced detail is presented to the detector for improved imaging. The variable...
