High image quality micro composite optical lens

A high image quality micro-compound optical lens comprises a drawtube and a light filter arranged at the bottom of the drawtube and is characterized in that the cavity of the drawtube is provided with a lens group, which comprises a first lens, a second lens, a third lens, and a fourth lens in turn. The first lens is a convexo-convex lens, the second a concavo- concavo lens, the third's first surface non-sphere concave and the second non-sphere convexo, and the fourth's first surface ellipsoid non-sphere surface, and the second surface hyperbola non-sphere surface. The utility model overcomes shortcomings of the current technologies and provides a high image quality micro-compound optical lens with 5-mega pixels, small cubage, small weight, even comparison, little color difference, and high image quality.
