Patent ID: 8194522

Claim:
An aspheric lens comprising at least one aspheric lens surface that is given by an equation Z ⁡ ( r ) = cr 2 1 + 1 - ( 1 + K ) ⁢ c 2 ⁢ r 2 + Lr 2 + Ar 4 + Br 6 + Cr 8 + Dr 10 + Er 12 + Fr 14 + Gr 16 + Hr 18 + Jr 20 where Z is a displacement of the at least one aspheric lens surface from a vertex of the aspheric lens, L≠0, c is a curvature, r 2 =x 2 +y 2 , K is a conic integer, and L and A through J are aspheric coefficients, wherein x and y are horizontal and vertical distances from the optical axis of the aspheric lens to determine a radius r from the optical axis to the at least one aspheric lens surface.
