Abstract: An optical imaging lens, including first to sixth lens elements sequentially arranged from an object side to an image side along an optical axis, is provided. Each lens element includes 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: (T3+G34)/T4?1.900 and (HFOV×ImgH)/EFL?50.000°, where T3 and T4 are thicknesses of the third and fourth lens elements along the optical axis, G34 is an air gap from the third lens element to the fourth lens element along the optical axis, HFOV is a half field of view of the optical imaging lens, ImgH is an image height of the optical imaging lens, and EFL is an effective focal length of the optical imaging lens.

Abstract: The present invention provides an optical imaging lens. The optical imaging lens comprises five lens elements positioned in an order from an object side to an image side, each of which has an object-side surface facing the object side and an image-side surface facing the image side. Counting from the object side to the image side, the five lens are labeled as a first lens element, a second lens element, a third lens element, a fourth lens element and a fifth lens element, all of which have refracting power. Through controlling a variable air gap formed between two adjacent lens elements and parameters to meet an inequality, adjustment distance required for focusing the optical imaging lens will be shortened.

Abstract: The present invention provides an optical imaging lens. The optical imaging lens comprises eight 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, the optical imaging lens may be provided with shortened system length, enlarged aperture, and increased image height and resolution, along with good imaging quality.

Abstract: The present invention provides an optical imaging lens. The optical imaging lens comprises eight 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, the optical imaging lens may be provided with shortened system length, reduced f number, and increased image height, along with good imaging quality.
