Abstract:
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, a third lens element, a fourth lens element and a fifth lens element, all of the first lens element, the second lens element, the third lens element, the fourth lens element and the fifth lens element having refractive power, said first to fifth 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 with positive refractive power, has an object-side surface, and the object-side surface is a convex surface; the second lens element with negative refractive power, has an image-side surface with a concave part in a vicinity of its periphery; the third lens element has an object-side surface with a concave part in a vicinity of its periphery; the fourth lens with positive refractive power, has an object-side surface and an image-side surface, the object-side surface is a concave surface and the image-side surface is a convex surface; the fifth lens has an object-side surface with a convex part in a vicinity of the optical axis, and an image-side surface with a concave part in a vicinity of the optical axis as well as a convex part in a vicinity of its periphery; the optical imaging lens set does not include any lens element with refractive power other than said first lens element, second lens element, third lens element, fourth lens element and fifth lens element, in addition, an air gap G
