WebDr. James T. Schwiegerling, Emeritus Professor of Optical Sciences, passed away on April 5, 2024. Jim had retired this past March from the University of Arizona after a valiant battle with cancer in which he prevailed for many years. A memorial will be held for Jim starting at 3PM on Friday, May 5 in the Meinel Auditorium at the Wyant College of Optical Sciences. WebMany optical eye models give accurate predictions only for small angles and small fields of view. If aberrations and image quality are important to consider, such 'paraxial' model eyes must be replaced by 'finite model' eyes incorporating features such as aspheric surfaces, tilts and decentrations, wavelength-dependent media and curved retinas.
