Abstract
A three-piece compact optical lens system includes, in order from the object side to the image side: a flat panel assembly made of glass, a first lens element with a negative refractive power having an object-side surface being concave near an optical axis; a stop; a second lens element with a positive refractive power having an object-side surface being convex near the optical axis and an image-side surface being convex near the optical axis; and a third lens element with a positive refractive power. Such a system can not only effectively collect light at a large angle, receive a wider range of images and achieve identification effects within very short distances, but also can reduce the distance between an object and the three-piece compact optical lens system, reduce the volume effectively and maintain its miniaturization.
