Embodiment Construction
[0020] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0021] Such as figure 1 As shown, a miniaturized high-pixel imaging optical system includes at least a first lens 1, a second lens 2, a third lens 3, a fourth lens 4, and a fifth lens in sequence from the object plane to the image plane along the optical axis. 5. The third lens 3 and the fourth lens 4 are bonded together to form a cemented lens, and the fifth lens 5 is a biconvex aspherical lens; the aperture ratio of the optical system is f / 2.4, and the optical system meets the following conditions:
[0022] (1)-1.2
[0023] (2) 0.45
[0024] (3...
