Embodiment 1

[0065] like Figure 1 to Figure 30 As shown, from the light-incident side of the imaging system to the light-emitting side of the imaging system includes the first lens, the second lens, the third lens, the fourth lens, the fifth lens, the sixth lens, the seventh lens, the eighth lens, the third lens Nine lenses. The first lens has optical power, the material of the first lens is glass material; the second lens has optical power; the third lens has positive optical power; the fourth lens has optical power; the fifth lens has optical power, and the third lens has optical power. The surface of the fifth lens toward the light-incident side is concave, the surface of the fifth lens toward the light-exit side is convex; the sixth lens has negative refractive power; the seventh lens has refractive power, and the surface of the seventh lens toward the light-incident side is concave , the surface of the seventh lens toward the light exit side is convex; the eighth lens has optical po...

Abstract

The invention provides an imaging system, which comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens from the light incident side to the light emergent side of the imaging system, a second lens; the third lens has positive focal power; the fourth lens has focal power; the surface, facing the light incident side, of the fifth lens is a concave surface, and the surface, facing the light emergent side, of the fifth lens is a convex surface; the sixth lens has negative focal power; the surface, facing the light incident side, of the seventh lens is a concave surface, and the surface, facing the light emergent side, of the seventh lens is a convex surface; the eighth lens has focal power; the surface, facing the light emitting side, of the ninth lens is a convex surface; wherein the half ImgH of the diagonal length of an effective pixel area on the imaging surface of the imaging system and the on-axis distance TTL from the surface, facing the incident side, of the first lens to the imaging surface meet the condition that TTL / ImgH is smaller than 1.3. The problem that in the prior art, an imaging system is poor in performance is solved.

Description

technical field [0001] The present invention relates to the technical field of optical imaging devices, and in particular, to an imaging system. Background technique [0002] In recent years, the quality of mobile terminal photography technology has largely determined its popularity with the public. High-pixel, large-aperture, and ultra-thin lenses have become a hot spot for manufacturers because of their clear photography and good-looking appearance. The photo is clearer, the large aperture is in the dark room or at night, and the photo performance is better in the environment with less light. The ultra-thin can better integrate the mobile phone lens and the mobile phone, and the camera part will not protrude, making the whole machine better. The performance of the current imaging system is not very good. [0003] That is to say, the imaging system in the prior art has the problem of poor performance. SUMMARY OF THE INVENTION [0004] The main purpose of the present inv...
