Abstract

The invention discloses a high-definition lens. A front lens group, a diaphragm, a rear lens group and an imaging surface are successively arranged from an object side to an image side, wherein the front lens group has the positive focal power; the rear lens group has the positive focal power; the front lens group comprises a first lens, a second lens and a third lens which are successively arranged from the object side to the image side; the focal power of the first lens and the focal power of the second lens are negative; the focal power of the third lens is positive; the rear lens group comprises a fourth lens, a fifth lens and a sixth lens which are successively arranged from the object side to the image side; the focal power of the fourth lens and the focal power of the sixth lens are positive; the focal power of the fifth lens is negative; the third lens, the fourth lens, the fifth lens and the sixth lens are all arranged as plastic aspherical lenses. The high-definition lens has the advantages of wide field angle, low cost, high definition and strong optical power.

Description

【Technical field】 [0001] The invention relates to a high-definition lens. 【Background technique】 [0002] At present, driving disputes and traffic accidents are common. In order to ensure driving safety, many cars are equipped with on-board cameras. However, the current general vehicle lens has a limited field of view, poor definition, and weak light transmission, so the current vehicle lens can no longer meet social needs. [0003] Therefore, the present invention is proposed based on the shortcomings of the above-mentioned prior art. 【Content of invention】 [0004] The object of the present invention is to overcome the deficiencies of the prior art and provide a high-definition lens with a large field of view, low cost, high definition and strong light transmission ability. [0005] The present invention is achieved through the following technical solutions: [0006] A high-definition lens is characterized in that: from the object side to the image side, there are seq...
