Problems solved by technology

[0003] As far as a six-piece lens structure is concerned, the distance from the object side of the first lens to the imaging surface on the optical axis is long in the past, which is not conducive to the thinning of portable electronic products or virtual reality devices, so it is extremely necessary to develop imaging Good quality lenses with reduced lens length
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 characteristics, and must also take into account the production and assembly yield. 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, which at least comprises first, second, third, fourth, fifth and six lenses from an object side to an image side in sequence. Through control of concave and convex surface arrangement of each lens and control of relevant parameters through at least one conditional expression, under the condition of maintaining good optical performance, lens length is reduced, angle of visual field is expanded and good thermal stability is achieved.

Description

technical field [0001] The invention relates to the field of optical components, in particular to an optical imaging lens, in particular to an optical imaging lens using at least six lenses. Background technique [0002] In recent years, the popularity of portable electronic products such as mobile phones, digital cameras, tablet computers, personal digital assistants (PDA), and even automotive electronic devices has made it possible to include optical imaging lenses, modular rear seat units, and image sensors. The image module is booming, and the thinness and lightness of portable electronic products also make the miniaturization demand of the image module higher and higher. With the photosensitive coupled device (Charge Coupled Device, referred to as CCD) Metal-Oxide Semiconductor (CMOS for short) technological progress and size reduction, the optical imaging lens installed in the image module also needs to be reduced in size, but the good optical performance of the optica...
