Dual focus diffractive optical element with extended depth of focus
Optical Review, 2014A dual focus property and an extended depth of focus were verified by a new type of diffractive lens displaying on liquid crystal on silicon (LCoS) devices. This type of lens is useful to read information on multilayer optical discs and tilted discs. The radial undulation of the phase groove on the diffractive lens gave the dual focus nature. The focal

Stress Birefringence for Extended Depth of Focus Imaging
International Optical Design Conference and Optical Fabrication and Testing, 2010A stressed element with sixfold symmetry can apodize a pupil with a superposition of positive and negative spherical aberrations. The point spread function for this system shows two marginal foci symmetrically separated from the paraxial focus, offering the possibility of using this type of element for extended depth of focus imaging.

Outcomes of extended depth of focus intraocular lenses implantation
Russian Annals of OphthalmologyExtended depth of focus (EDOF) intraocular lenses (IOLs) are the latest IOL designs. In recent years, several models of EDOF IOLs have become available in Russia, two of which (Tecnis Symfony and Acrysof IQ Vivity) are implanted in our clinic. Comparative studies devoted to the results of implantation of the new EDOF IOLs are rare in the available ...
