Abstract
An optical lens system, sequentially arranged from an object side to an image side along an optical axis, includes: a stop, a first lens element with positive refractive power having a convex object-side surface, a second lens element with negative refractive power, a third lens element with positive refractive power having a concave object-side surface and a convex image-side surface, and a fourth lens element with negative refractive power having a concave image-side surface with both being aspheric. Furthermore, the optical lens system satisfies conditions related to increase the field of view and reduce the total length as well as the sensitivity of assembly tolerance of the optical lens system.
