Abstract
An optical lens system with a wide field of view includes, in order from the object side to the image side: a stop, a first lens element with a positive refractive power, a second lens element with a negative refractive power, and a third lens element with a positive refractive power. A focal length of the first lens element and the second lens element combined is f12, a focal length of the third lens element is f3, and they satisfy the relation: 0.3<f12/f3<0.9, so that the optical lens system has a wide field of view, high resolution, short length and less distortion.
