Present embodiments provide for optical imaging lenses. An optical imaging lens may include at least seven lens elements positioned sequentially from an object side to an image side. Through arrangement of the convex or concave surfaces of the lens elements, the length of the optical imaging lens may be shortened while providing better optical characteristics and imaging quality.

Optical imaging lens

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, and a sixth lens element from an object side to an image side in order along an optical axis. The first lens element to the sixth lens element each include an object-side surface facing the object side and allowing imaging rays to pass through and an image-side surface facing the image side and allowing the imaging rays to pass through. The optical imaging lens satisfies: EFL/(T1+T3)&#x2265;2.300. EFL is an effective focal length of the optical imaging lens. T1 is a thickness of the first lens element along the optical axis. T3 is a thickness of the third lens element along the optical axis.

An optical lens assembly is provided. The optical lens assembly includes first, second, third and fourth lens elements having refracting power arranged along an optical axis in a sequence from a light output side to a light input side. The first lens element is arranged to be a lens element in a fourth order from the light input side to the light output side. The second lens element is arranged to be a lens element in a third order from the light input side to the light output side. The third lens element is arranged to be a lens element in a second order from the light input side to the light output side. The fourth lens element is arranged to be a lens element in a first order from the light input side to the light output side.

Four lens optical lens assembly having specified total Abbe number

An optical imaging lens includes a first lens element to a sixth 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 image-side surface of the first lens element is convex, a periphery region of the object-side surface of the third lens element is convex, an optical axis region of the image-side surface of the third lens element is convex, 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 image-side surface of the sixth lens element is convex. The optical imaging lens has only the above six lens elements with refractive power, and the optical imaging lens satisfies the following conditions: &#x3c5;3+&#x3c5;4+&#x3c5;5&#x2264;130.000.

The present invention provides an optical imaging lens. The optical imaging lens comprises six lens elements positioned in an order from an object side to an image side. Through controlling the convex or concave shape of the surfaces of the lens elements, such as convex peripheral portion on the object-side surface of the first lens element, convex peripheral portion on the image-side surface of the third lens element, convex peripheral portion on the object-side surface of the fifth lens element, concave peripheral portion on the object-side surface of the sixth lens element and convex peripheral portion on the image-side surface of the sixth lens element, and designing parameters satisfying at least one inequality, the optical imaging lens may shorten system length and promote thermal stability.
