Problems solved by technology

[0003] As far as the five-element 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. Therefore, it is extremely necessary to develop imaging quality Good lens 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 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 provides an optical imaging lens, which sequentially includes at least first, second, third, fourth and fifth lenses from the object side to the image side. The present invention shortens the length of the lens and increases the angle of view and the amount of incoming light by controlling the arrangement of the convex and concave surfaces of each lens while maintaining good optical performance.

Description

technical field [0001] The invention relates to the field of optical imaging lenses, in particular to an optical imaging lens. Background technique [0002] In recent years, the popularization of mobile phones, digital cameras, tablet computers, personal digital assistants (Personal Digital Assistant, PDA) and other portable electronic products, and even automotive electronic devices has made the image With the vigorous development of modules, the thinner and lighter portable electronic products have also increased the miniaturization requirements of image modules. , referred to as CMOS) 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 optical imaging lens is also necessary to take into account. If the image module is used in a vehicle camera device, even in order to cope with driving and low-light environments, the improvement of the view angle of the ...
