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...
