Patent ID: 11347029

Abstract:
A camera lens or lens group of reduced overall length includes a first lens with positive power, a second lens with negative power, a third lens with positive power, and an imaging element. The first, object side, lens includes a first surface and a second surface, the second lens includes a third surface and a fourth surface, and the third lens includes a fifth surface and a sixth surface. The camera lens satisfies conditions of 1.00<D/TTL<1.25; 0.85<|F1|/|F|<0.95; 3.85<|F2|/|F|<4.15; and 21.50<|F3|/|F|<27.50. D is the maximum imaging circle diameter on the imaging surface, TTL is the distance from the center point to the imaging side of the object-side surface of the first lens, F is the total focal length of the camera lens, F1 is the focal length of the first lens, F2 is the focal length of the second lens, and F3 is the focal length of the third lens.
