Patent ID: 8373937

Claim:
A miniaturized optical lens system comprising, in order from an object side to an image side: a first lens element with positive refractive power having a convex object-side surface and a concave image-side surface, at least one of the object-side and the image-side surfaces of the first lens element being aspheric; a second lens element with negative refractive power having a concave object-side surface and a convex image-side surface, at least one of the object-side and the image-side surfaces of the second lens element being aspheric; wherein there are two lens elements with refractive power and an aperture stop in the miniaturized optical lens system; wherein an Abbe number of the first lens element is V 1 , an Abbe number of the second lens element is V 2 , a focal length of the miniaturized optical lens system is f, a focal length of the second lens element is f 2 , a radius of curvature of the object-side surface of the second lens element is R 3 , a distance from the aperture stop to an image plane along an optical axis is SL, a distance from the object-side surface of the first lens element to the image plane along the optical axis is TTL, and they satisfy the relations: 15 <|V 1 −V 2|<48; −0.43 <f/f 2<0; −1.20 <R 3 /f<− 0.50; 0.9 <SL/TTL< 1.1.
