Abstract

One embodiment of the invention discloses a miniaturized high-pixel shooting optical system. The system at least successively comprises a first lens, a second lens, a third lens, a fourth lens and a fifth lens from an object surface to an image surface along an optical axis, wherein the third lens and the fourth lens are bonded to each other to form a gummed lens, and the fifth lens is a double-convex aspheric lens; and the caliber ratio of the optical system is f / 2.4, the optical system satisfies the following conditions: 1), -1.2<f / f1<-0.6; 2), 0.45<f / f2<0.95; 3), -0.7<f / f34<-0.35, and 0.7<f / f5<1.25. On the other hand, another embodiment of the invention also provides a lens. According to the embodiments of the invention, the lens has a super wide viewing angle; at the same time, the optical total length of the optical system or the lens is shortened, and miniaturization of the optical system or the lens is realized; and besides, the optical system and the lens have excellent performance of providing total-interface clear images with more than four million pixels.

Description

Technical field: [0001] The invention relates to an imaging optical system and a lens applied thereto, in particular to a miniaturized imaging optical system and lens which can be applied to wearable devices, sports cameras and other equipment. Background technique: [0002] In order to improve the performance of existing imaging optical systems or lenses, there are problems that the total optical length of the optical system is too long, or the number of lenses is too large, or the field of view is narrow. Invention content: [0003] In order to overcome the problems in the prior art that the total optical length is too long, or the number of lenses is too large, or the field of view is narrow, the embodiments of the present invention provide a miniaturized high-pixel imaging optical system on the one hand. [0004] A miniaturized high-pixel imaging optical system, which sequentially includes at least a first lens, a second lens, a third lens, a fourth lens, and a fifth l...
