ABSTRACT:
A unitary lens and light emitting device combination is provided that produces a highly uniform beam of light, corrected for distortions and gaps in illumination, throughout a full output beam width. The unitary lens incorporates all of the necessary optical surfaces to provide the output beam, including a pattern-correcting spherical refracting surface that smooths intensity variations in the overall illumination pattern.
