Abstract

The invention discloses an optical imaging lens set and an imaging device using the optical imaging lens set. The optical imaging lens set sequentially includes: a first lens, a second lens, and a third lens along the optical axis from the object side to the image side , the fourth lens, the fifth lens and the sixth lens; wherein the focal length of the optical imaging lens group is f, the distance between the fourth lens and the fifth lens on the optical axis is T45, and the first lens to the sixth lens are adjacent to each other The sum of the distances between the lenses on the optical axis is AAT, the distance from the object-side surface of the first lens to the imaging surface on the optical axis is TL, and the optical imaging lens group meets the following conditions: 0.3≤T45 / (AAT‑T45) ≤0.7; and 0.8≤TL / f≤1. The above optical imaging lens group can maintain high imaging quality while effectively shortening the length of the system, and has telephoto characteristics to meet the telephoto requirements; and enables the camera device using the optical imaging lens group to have high-level imaging quality, At the same time, the volume is light and thin, easy to carry.

Description

technical field [0001] The invention relates to the technical field of optical mirror group equipment, in particular to an optical imaging lens group and an imaging device using the optical imaging lens group. Background technique [0002] With the rapid upgrading of related consumer electronic products such as smart phones, portable computers and tablet devices, the market has higher and higher requirements for the quality of optical imaging lenses of electronic products. The refinement of semiconductor manufacturing technology has reduced the pixel size of photosensitive devices, and the optical imaging system has gradually developed into the field of high pixels, which also puts forward higher requirements for imaging quality. Not only are optical imaging lenses required to have performances such as miniaturization, large aperture, and high resolution, but sometimes optical imaging lenses are also required to have characteristics such as telephoto. [0003] The optical s...
