Abstract

The invention relates to an optical imaging lens, which sequentially comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens and a ninth lens from an object side to an image side along an optical axis, wherein each of the first to ninth lenses includes an object side surface facing the object side and allowing imaging light to pass through and an image side surface facing the image side and allowing the imaging light to pass through, the lenses of the optical imaging lens are only the nine lenses, the second lens has a negative refractive index, the fourth lens has a negative refractive index, the optical axis area of the object side surface of the seventh lens is a concave surface, and the optical axis area of the image side surface of the ninth lens is a concave surface.

Description

technical field [0001] The present invention relates to an optical component, and in particular to an optical imaging lens. Background technique [0002] In recent years, optical imaging lenses have continued to evolve. In addition to requiring optical imaging lenses to be thin and compact, it is also becoming more and more important to improve the imaging quality of lenses such as aberration and chromatic aberration. However, increasing the number of optical lenses according to the demand will increase the distance on the optical axis from the object side of the first lens to the imaging surface, which is unfavorable for the thinning of mobile phones and digital cameras. [0003] Therefore, it has always been a design development goal to provide an optical imaging lens that is thin, light, small and has good imaging quality. In addition, a small aperture value can increase the amount of light passing through, and a large image height can moderately increase the pixel size ...
