Abstract:
An optical lens assembly includes, in order from an object side to an image side, a first lens element, a second lens element and a third lens element. The first lens element with positive refractive power has an object-side surface being convex, and the object-side surface and an image-side surface thereof are aspheric. The second lens element with negative refractive power has an image-side surface being concave, and an object-side surface and the image-side surface thereof are aspheric. The third lens element with refractive power has an object-side surface being concave, and the object-side surface and an image-side surface thereof are aspheric. The optical lens assembly further includes a stop with no lens element having refractive power disposed between the stop and the first lens element. The optical lens assembly has a total of three lens elements with refractive power.
