摘要： An optical imaging lens includes a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element, a sixth lens element and a seventh lens element arranged in order from an object side to an image side along an optical axis. Each lens element has an object-side surface and an image-side surface. The first lens element has positive refracting power, and the image-side surface of the first lens element has a concave portion in a vicinity of a periphery. The third lens element has negative refracting power, and the image-side surface of the third lens element has a concave portion in a vicinity of a periphery. At least one of the object-side surface and the image-side surface of the fourth lens element is aspheric surface, and at least one of the object-side surface and the image-side surface of the fifth lens element is aspheric surface. The sixth lens element has positive refracting power, and the image-side surface of the seventh lens element has a concave portion in a vicinity of the optical axis.

摘要： 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 ν3 of the third lens element and the Abbe number ν5 of the fifth lens element satisfy |ν3−ν5|≤25.

摘要： Present embodiments provide for a mobile device and an optical imaging lens thereof. The optical imaging lens comprises an aperture stop and five lens elements positioned sequentially from an object side to an image side. By controlling the convex or concave shape of the surfaces of the lens elements and designing parameters satisfying at least one inequality, the optical imaging lens may exhibit better optical characteristics and the total length of the optical imaging lens may be shortened.
