Abstract

An optical imaging lens includes a first lens element to a seventh lens element from an object side to an image side in order along an optical axis, and each lens element has an object-side surface and an image-side surface. An optical axis region of the object-side surface of the third lens element is convex, an optical axis region of the object-side surface of the fourth lens element is concave, an optical axis region of the image-side surface of the fifth lens element is concave, the sixth lens element has positive refracting power and a periphery region of the object-side surface of the sixth lens element is concave, an optical axis region of the object-side surface of the seventh lens element is concave, and the optical imaging lens satisfies the conditions: υ2+υ3+υ6≤110.000 and (T1+T7)/(G12+T2+G45)≥2.500.
