Abstract
An optical imaging lens has six lens elements. A periphery region of the image-side surface of the first lens element is concave, an periphery region of the object-side surface of the third lens element is concave, an optical axis region of the object-side surface of the sixth lens element is concave, a periphery region of the object-side surface of the sixth lens element is convex, an optical axis region of the image-side surface of the sixth lens element is concave and a periphery region of the image-side surface of the sixth lens element is convex. AAG is a sum of five air gaps, T6 is a thickness of the sixth lens element and the Abbe number of the second, the third, the fourth, the fifth is ν2, ν3, ν4 and ν5 to satisfy ν2+ν3+ν4+ν5≤135.000 and AAG/T6≤2.900.
