Present embodiments provide for optical imaging lenses. An optical imaging lens may comprise six 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, the total length of the optical imaging lens may be shortened and the performance of athermalization may be improved.

Optical imaging lens

An optical imaging lens includes a first lens of negative refractive power, a second lens of negative refractive power and of an image-side surface with a concave portion near its optical-axis, a third lens of an object-side surface with a convex portion near its optical-axis and an image-side surface with a convex portion near its optical-axis, a fourth lens of an object-side surface with a convex portion near its optical-axis, a fifth lens of an object-side surface with a concave portion near its periphery and an image-side surface with a concave portion in a vicinity of its optical-axis and a six lens of an image-side surface with a convex portion near its optical-axis. ALT is a total thickness of all six lens elements, AAG is a sum of all five air gaps and the first lens element has a first lens element thickness Tto satisfy ALT/Tor AAG/T&#x2264;4.71.

An imaging lens includes first, second, third, fourth, fifth, sixth and seventh lens elements arranged in a sequence 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 object-side of the third lens element has a convex portion in a vicinity of a periphery. The object-side of the fifth lens element has a convex portion in a vicinity of the optical axis and a concave portion in a vicinity of a periphery. The object-side of the sixth lens element has a concave portion in a vicinity of a periphery. All of lens elements having refracting power of the imaging lens are the first, second, third, fourth, fifth, sixth and seventh lens elements.'

Present embodiments provide for an optical imaging lens. The 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 seven lens element positioned in an order from an object side to an image side. Through the arrangement of convex or concave surfaces of the seven lens elements, the length of the optical imaging lens may be shortened while providing better optical characteristics and imaging quality.
