Optical imaging lens

Abstract

The invention provides an optical imaging lens. The optical imaging lens sequentially comprises a first lens, an aperture, a second lens, a third lens, a fourth lens and a fifth lens from an object side to an image side along an optical axis, the optical imaging lens satisfies the conditional expressions of V2+V3+V4+V5<=170.000 and (T2+T4) / (T1+G12)>=2.900. In addition, other optical imaging lensesare also provided. The optical imaging lens can have a large field angle, the area ratio occupied by the optical imaging lens when the optical imaging lens is arranged on a shooting device is reduced, the length of the optical imaging lens is shortened, and good imaging quality is kept.

Description

technical field [0001] The invention relates to the field of optical imaging, in particular to an optical imaging lens. Background technique [0002] In recent years, optical imaging lenses have continued to evolve. In addition to requiring thinner and smaller optical imaging lenses, it is also more and more important to expand the field of view of optical imaging lenses and improve imaging quality such as lens aberration and chromatic aberration. [0003] However, in response to the demand, if the distance between the object side of the first lens and the imaging surface on the optical axis of the optical imaging lens increases, it will be unfavorable for the thinning of mobile phones and digital cameras. Optical imaging lenses with good imaging quality have always been the development goal of design. Furthermore, the smaller the area ratio occupied by the optical imaging lens set in the shooting device, it will also be one of the trends in future design. Contents of the...
