An optical lens set includes a first lens element of an object-side surface with a convex portion in a vicinity of an optical axis, a second lens element of an image-side surface with a concave portion in a vicinity of its periphery and a sixth lens element of an image-side surface with a convex portion in a vicinity of its periphery. Tmin is the minimal distance from the object-side surface of the fifth lens element to the image-side surface of the fifth lens element and the fifth lens element has a fifth lens element thickness Talong the optical axis to satisfy Tmin/T≤0.6.

Optical lens set

An optical lens set includes no air gap between the first lens element and the second lens element, the third lens element of a concave object-side surface near its optical-axis, and the sixth lens element of a convex image-side surface near its periphery. The Abbe number &#x3bd;3 of the third lens element and the Abbe number &#x3bd;5 of the fifth lens element satisfy |&#x3bd;3&#x2212;&#x3bd;5|&#x2264;25.

An optical-lens-set includes a first lens of a convex object surface near the optical-axis, a second lens of negative refractive power of an object surface with a convex portion near the optical-axis and a convex portion near its periphery, a third lens of a convex image surface near its periphery, a fourth lens of a concave object surface near its periphery and a convex image surface near its periphery, a fifth lens of a concave object surface near its periphery and an image surface with a convex portion near the optical-axis and a convex portion near its periphery, a sixth lens of a concave image surface near the optical-axis so that an F-number, the total thickness ALT of all six lens, an air gap Gbetween the third lens and the fourth lens and an air gap Gbetween the fourth lens and the fifth lens satisfy F-number&#x2264;1.8 and ALT/(G+G)&#x2265;9.0.
