Abstract

The embodiment of the invention discloses a large-aperture ultra-large wide-angle monitoring camera module. The large-aperture ultra-large wide-angle monitoring camera module sequentially comprises afirst lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens from an object plane to an image plane along an optical axis, the object plane side of the first lens is a convexsurface, the image plane side of the first lens is a concave surface, and the focal power is negative; the object plane side of the second lens is a concave surface, the image plane side of the secondlens is a convex surface, and the focal power of the second lens is positive; the object plane side of the third lens is a convex surface, the image plane side of the third lens is a convex surface,and the focal power of the third lens is positive; the object plane side of the fourth lens is a concave surface, the image plane side of the fourth lens is a concave surface, and the focal power is negative; the image surface side of the fifth lens is a convex surface, the image surface side of the fifth lens is a convex surface, and the focal power of the fifth lens is positive; the object planeside of the sixth lens is a convex surface, the image plane side of the sixth lens is a concave surface, and the focal power of the sixth lens is positive. The optical system is mainly composed of the six lenses, and is reasonable in lens number, simple in structure, small in size, light in weight and low in cost.

Description

Technical field: [0001] The invention relates to a camera module, in particular to a large aperture super wide-angle monitoring camera module suitable for the monitoring field. Background technique: [0002] With the development of society and the continuous improvement of people's living standards, visible smart doorbells are now widely used in high-end residential buildings in various communities. The key core of the visual smart doorbell is the camera module, but the camera module has the problems of complex structure, large volume, small viewing range, poor night vision effect, and poor clarity. And in actual use, there is serious heating, which leads to the phenomenon of virtual focus in imaging. Invention content: [0003] In order to overcome the problems of complex structure and large volume in the existing camera module, an embodiment of the present invention provides a monitoring camera module with a large aperture and a super wide angle. [0004] A large-apert...
