Problems solved by technology

The existing optical imaging lens is thick and heavy, and the design of aperture value and field of view angle cannot meet the market demand
[0003] As far as the eight-element lens structure is concerned, the distance on the optical axis from the object side of the first lens to the imaging surface is designed to be long in the past, which is not conducive to the thinning of portable electronic products
However, the design of optical imaging lens is not simply to scale down the lens with good imaging quality to produce an optical imaging lens with both imaging quality and miniaturization. The design process involves material properties, and production and assembly yields must also be taken into consideration. Due to practical problems in production, the technical difficulty of miniaturized lenses is obviously higher than that of traditional lenses

Abstract

The invention discloses an optical imaging lens unit comprising a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens, and an eighth lens arranged in sequence from an object side to an image side. According to the invention, with control of concave-convex curved surface arrangement of all lenses, the lens unit is shortened, the field angle is increased, and the diaphragm value is reduced while the good optical performance is kept.

Description

technical field [0001] The invention relates to the field of optical imaging, in particular to an optical imaging lens. Background technique [0002] The specifications of portable electronic products are changing with each passing day, and its key components - optical imaging lenses are also becoming more diversified. They not only pursue thinness and good imaging quality, but also pursue designs with larger apertures and field of view. The existing optical imaging lens is thick and heavy, and the design of the aperture value and the angle of view cannot meet the market demand. [0003] As far as the eight-element lens structure is concerned, the distance on the optical axis from the object side of the first lens to the imaging surface is designed to be long in the past, which is not conducive to the thinning of portable electronic products. However, the design of optical imaging lens is not simply to scale down the lens with good imaging quality to produce an optical imag...
