Abstract:
1. A lens element comprising: a housing defining a center bore there through, the bore defining an optical axis; a light transmissive cover coupled to the housing; a first elastic solid lens disposed within the housing along the optical axis and characterized by a first durometer hardness, the first elastic solid lens having a first surface oriented toward a light source and an opposing second surface adjacent the light transmissive cover, the first and second surfaces of the first lens defining a first lens thickness; and a second elastic solid lens having a first surface oriented toward the light source and an opposing second surface adjacent and substantially conforming to the first surface of the first elastic solid lens, the first and second surfaces of the second lens defining a second thickness, the second lens characterized by a second durometer hardness; wherein the second lens thickness is less than the first lens thickness and the second durometer hardness is greater than the first durometer hardness.
