Problems solved by technology

However, in the design process of an optical lens, increasing the aperture means increasing the light flux, which also means a higher signal-to-noise ratio while increasing the light flux. A larger signal-to-noise ratio is not conducive to improving the imaging of the optical imaging lens. quality

Description

technical field [0001] The present application relates to the field of optical elements, in particular, to an optical imaging lens. Background technique [0002] In recent years, with the increasingly powerful camera and photography functions of smart phones, people are more and more fond of using smart phones to take pictures and videos in their daily life to record every bit of life. Therefore, a smart phone with a powerful shooting function has become an essential thing for people to live in and travel. At the same time, in order to meet the market demand of smart phones and to open up a broader market, major mobile phone manufacturers have put forward more requirements for mobile phone lenses. [0003] A lens with characteristics such as large aperture, large image area, ultra-thin, wide-angle, and small head has been widely favored by many mobile phone developers. However, in the design process of an optical lens, increasing the aperture means increasing the light flu...
