Aspheric lenses and optical assemblies for generating uniform rectangular irradiance distributions

Abstract

A lens assembly comprising one or more lenses is provided. The one or more lenses together comprise a first surface and a second surface. An optical axis of the lens assembly extends in the z-direction. The first surface comprises a first cross-section in a y-z plane, wherein the first cross-section comprises an aspheric first curve that varies in the y-z plane, wherein the first aspheric curve is non-circular, non-elliptical, and non-conical. One surface selected from the first surface and the second surface comprises a second cross-section in a x-z plane, wherein the second cross-section comprises an aspheric second curve in the x-z plane, wherein the second first aspheric curve is non-circular, non-elliptical, and non-conical.
