Abstract
The embodiments of the present invention relate to the technical fields of optics. Disclosed is an optical imaging lens, wherein the optical imaging lens comprises six lenses in total, the six lenses being sequentially arranged from an object side to an image side and comprising: a first lens having a negative refractive power, a second lens having a positive refractive power, a third lens having a positive refractive power, a fourth lens having a negative refractive power, a fifth lens having a positive refractive power, and a sixth lens having a negative refractive power. The described lens configuration enables the optical imaging lens to exhibit large aperture, wide-angle, ultra-thin, and good optical performance characteristics, and is capable of controlling an optical total length of the optical imaging lens, reasonably distributing lens focal length, moderating the degree to which light is deflected through lenses, effectively correcting astigmatism and distortion, correcting chromatic aberrations, reducing aberrations, and improving imaging performance.
