Abstract
The invention discloses an optical imaging lens set. The optical imaging lens set comprises a prism which is configured such that light entering the prism along the direction of a Y optical axis is reflected and then is emitted from the prism along the direction of an X optical axis, wherein the X optical axis is perpendicular to the Y optical axis. The optical imaging lens set further comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens which are sequentially distributed from the prism to an image side along the X optical axis; the first lens has positive focal power; the second lens has negative focal power; the third lens has focal power; the object side surface of the third lens is a convex surface; the image side surface of the third lens is a concave surface; the fourth lens has focal power; the object side surface of the fourth lens is a concave surface; the image side surface of the fourth lens is a convex surface; the fifth lens has focal power; the object side surface of the fifth lens is a convex surface; the sixth lens has focal power; a distance TTL from the object side surface of the first lens to an imaging surface on an optical axis and the total effective focal length f of the optical imaging lens set meet a relational expression that TT / f<1; and the central thickness CT1 of the first lens on the optical axis, the central thickness CT2 of the second lens on the optical axis and the central thickness CT3 of the third lens on the optical axis satisfy a relational expression that 3.0<CT1 / (CT2+CT3)< 3.5.
Description
technical field [0001] The present application relates to an optical imaging lens set, more specifically, to an optical imaging lens set including six lenses and one prism. Background technique [0002] In recent years, with the development of science and technology, the market demand for imaging systems suitable for portable electronic products has gradually increased. In order to meet the needs of various shooting scenarios, the lens modules mounted on portable terminals such as mobile phones are also gradually changing from single-camera lenses to multi-camera lenses. Multi-camera lenses often have a telephoto imaging system. When shooting with conventional telephoto lenses, the shooting is often unstable due to the traditional telescopic manipulation mode. In addition, conventional telephoto lenses usually have a long optical length, which cannot be adapted to the increasingly miniaturized portable electronic products. Contents of the invention [0003] The present ...
