Optical lens assembly
An optical lens assembly includes a first lens element, a second lens element, a third lens element, and a fourth lens element from an object side to an image side in order along an optical axis. The first lens element to the fourth lens element each include an object-side surface facing the object side and allowing imaging rays to pass through and an image-side surface facing the image side and allowing the imaging rays to pass through. The object-side surface of the first lens element has a convex portion in a vicinity of the optical axis. The second lens element has positive refracting power, and the object-side surface of the second lens element has a concave portion in a vicinity of a periphery of the second lens element. The third lens element is made of glass having an Abbe number greater than 60.
