Problems solved by technology

[0002] At present, science and technology are changing with each passing day, and optical lenses are also developing towards the characteristics of full spectrum, large image area, and high resolution. At present, the existing lenses are difficult to meet the market demand in terms of pixels, performance and cost, especially in the current market. The monitoring distance of the front-view lens is within 100 meters, and the monitoring images at a longer distance cannot be clearly presented

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] like Figure 1-4 As shown, a 5.4mm large-aperture high-definition lens: a 5.4mm large-aperture high-definition lens: includes a first meniscus negative lens 1, a second meniscus positive lens 2, and a third meniscus lens arranged sequentially along the incident light path from front to back. Convex positive lens 3, aperture 4, fourth meniscus negative lens 5, fifth biconvex positive lens 6, sixth meniscus positive lens 7, all lenses are made of glass;

[0023] The object side of the first meniscus negative lens is convex, and the image side is concave; the object side of the second meniscus positive lens is concave, and the image side is convex; the third plano-convex positive lens has a convex object side, and the image side is flat The object side of the fourth meniscus negative lens is convex, and the image side is concave; the objec...

Abstract

The invention relates to a 5.4 mm large-aperture high-definition lens and an imaging method thereof. The 5.4 mm large-aperture high-definition lens comprises a first negative meniscus lens, a second positive meniscus lens, a third positive plano-convex lens, a diaphragm, a fourth negative meniscus lens, a fifth positive biconvex lens and a sixth positive meniscus lens which are sequentially arranged from front to back along an incident light path, and the fourth lens and the fifth lens are cemented with each other to form a first cemented group. According to the 5.4 mm large-aperture high-definition lens, the structure is simple, the design is reasonable, the long-distance formed image quality is clear, and the eight-megapixel camera shooting requirement is completely met.

Description

technical field [0001] The invention relates to a 5.4mm large-aperture high-definition lens and an imaging method thereof. Background technique [0002] At present, science and technology are changing with each passing day, and optical lenses are also developing towards the characteristics of full spectrum, large image area, and high resolution. At present, the existing lenses are difficult to meet the market demand in terms of pixels, performance and cost, especially in the current market. The monitoring distance of the forward-looking lens is within 100 meters, and the monitoring images at a longer distance cannot be clearly presented. Contents of the invention [0003] In view of the problems existing in the above-mentioned existing lenses, the present invention proposes a 5.4mm large-aperture high-definition lens and an imaging method thereof. [0004] The solution adopted by the present invention to solve the technical problem is a 5.4mm large-aperture high-definitio...
