The embodiments of the invention disclose a high-pixel intelligent shooting optical system. The system at least successively comprises a first lens, a second lens, a third lens and a fourth lens from an object surface to an image surface along an optical axis, wherein the first lens is a double-concave negative lens; the second lens is an aspheric double-convex positive lens; and the third lens and the fourth lens are bonded to each other to form a gummed lens and have positive focal power. The optical system satisfies the following conditions: 1), -3<f1 / f<-0.9; 2), 1.2<f2 / f<3; 3), 2.4<f34 / f<5, wherein f1 indicates the focal length of the first lens, f2 indicates the focal lens of the second lens, f34 indicates a combined focal lens after the third lens and the fourth lens are bonded to each other to form the gummed lens, and f is an effective focal lens of the whole optical system. The embodiments of the invention further disclose a lens. According to the invention, the optical system and the lens can ensure that the whole optical lens or the lens has high-performance imaging quality and day and night confocal performance, thereby being suitable for an intelligent household safety protection system.
Description
[0001] Technical field: [0002] The invention relates to a high-pixel intelligent imaging optical system and a lens applied thereto, in particular to a high-pixel intelligent imaging optical system and a lens applied to a smart home security system (such as a video doorbell or an IPCamera camera, etc.). [0003] Background technique: [0004] The current smart camera optical system or lens used in smart home security systems, in order to reduce costs, has the problem of not being able to guarantee high-performance imaging quality and day and night confocal. [0005] Invention content: [0006] In order to overcome the problems of inability to guarantee high-performance imaging quality and day-night confocal in the prior art, the embodiments of the present invention provide a high-pixel intelligent camera optical system on the one hand. [0007] A high-pixel intelligent imaging optical system, which sequentially includes at least a first lens, a second lens, a third lens, and ...
