Abstract:
An optical lens includes a first lens group with a negative refractive power, a second lens group with a positive refractive power, and an aperture stop disposed between the first lens group and the second lens group. The second lens group is disposed between the first lens group and the second side. The optical lens satisfies the conditions: 2.1<D1/D3<3.0 and 1.9<D1/DL<3.2, where D1 is a diameter of a surface of the first lens facing the first side, D3 is a diameter of a surface of the third lens facing the first side, DL is a diameter of a surface of a last lens facing the second side, and the last lens is nearest the second side as compared with any other lens of the optical lens.

Claim (Index 20):
The fabrication method as claimed in  claim 19 , wherein the optical lens satisfies the conditions:\n 0.146<IH/TTL<0.174 and 0.023<IH/FOV<0.026, where IH is a semi-diagonal image height on an image plane, TTL is a total track length that is a distance along an optical axis between a surface of the first lens facing the magnified side and a surface of the last lens facing the minified side, and FOV is a full field of view of the optical lens.
