An optical imaging lens group and an imaging device using the optical imaging lens group

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 from the object side surface of the first lens to the imaging plane on the optical axis is TL, and the first The effective radius of the image-side surface of the lens is SD12, the effective radius of the image-side surface of the second lens is SD22, and the optical imaging lens group satisfies the following conditions: 0.1≤SD12‑SD22≤0.3; and 0.9≤TL / f≤1 . The above-mentioned optical imaging lens group ensures high-level imaging quality by matching the surface structure of each lens with the optical parameters, and can maintain high imaging quality under the premise of effectively shortening the system length, so that the optical imaging lens group has a telephoto characteristics and meet the telephoto requirements, and at the same time make the camera device using the optical imaging lens group thin and portable.

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. This not only requires optical imaging lenses to have performances such as miniaturization, large aperture, and high resolution, but also sometimes requires optical imaging lenses to have telephoto characteristics. In addition, for some electronic ...

Problems solved by technology

[0003] The optical system of traditional long-distance shooting mostly adopts a multi-chip structure and is equipped with a spherical glass lens. This configuration makes the lens too bulky and difficult to carry. It is not suitable for consumer electronics products that are becoming thinner, lighter and more portable, and the cost is high.
