Claim:
1. An optical imaging lens set, from an object side toward an image side in order along an optical axis comprising: an aperture stop, a first lens element, a second lens element and a third lens element, said first to third lens elements having an object-side surface facing toward the object side as well as an image-side surface facing toward the image side, wherein: the first lens element has positive refractive power, an object-side surface with a convex part in a vicinity of the optical axis, and a convex part in a vicinity of its periphery; the second lens element has positive refractive power, an object-side surface with a concave part in a vicinity of the optical axis, and a concave part in a vicinity of its periphery, an image-side surface with a convex part in a vicinity of the optical axis; and the third lens element has negative refractive power, an image-side surface with a concave part in a vicinity of the optical axis, and a convex part in a vicinity of its periphery; wherein a sum of both of two air gaps AAG between each lens element from said first lens element to said third lens element along the optical axis, a thickness T1 of said first lens element along said optical axis, a thickness T2 of said second lens element along said optical axis, a thickness T3 of said third lens element along said optical axis, an Abbe number V1 of the first lens element, an Abbe number V2 of the second lens element, and an Abbe number V3 of the third lens element satisfy the relationships AAG/T3≦1.1, T2/T1≦1.45, AAG/T1≦1.2, and |V1−V2|≦10.0, in addition, the optical imaging lens set does not include any lens element with refractive power other than said first, second and third lens elements.
