Abstract
An optical emitter providing improved light uniformity. The optical emitter includes a light source and a lens element spaced apart from the light source such that no additional lens elements are positioned therebetween. The lens element includes an inner light-receiving surface within the Fresnel field of the light source. In some embodiments, the light source includes an LED array and the lens element includes a lens array. The optical emitter provides the ability to adjust focus or spot size while not degrading the uniformity of the light intensity.
