| titleOfInvention | Optical imaging lens |
| abstract | The present application discloses an optical imaging lens, which includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens in sequence from the object side to the image side along the optical axis, wherein, The first lens has positive refractive power, its object side is convex, and its image side is concave; the second lens has negative refractive power; the third lens has refractive power; the fourth lens has refractive power, and its object side is convex, The image side is concave; the fifth lens has positive refractive power; the sixth lens has negative refractive power. The value of the effective focal length f1 of the first lens is 3.98mm, the value of the effective focal length f5 of the fifth lens is 4.22mm, and the value of the effective focal length f6 of the sixth lens is ‑2.85mm; the object side of the first lens is to the imaging lens The on-axis distance TTL of the imaging surface, the effective focal length f of the optical imaging lens, the half of the diagonal length of the effective pixel area on the imaging surface ImgH, and the entrance pupil diameter EPD of the optical imaging lens satisfy ImgH/TTL=0.77 and f/EPD= 1.84. |
