Embodiment Construction

[0022] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0023] Such as figure 1 As shown, the ultra-wide-angle, low-distortion, and high-pixel optical system sequentially includes at least a first lens 1, a second lens 2, a third lens 3, a fourth lens 4, and a fifth lens 5 along the optical axis from the object plane to the image plane. The sixth lens 6 and the seventh lens 7 .

[0024] The object plane side of the first lens 1 is a convex surface, the image plane side is a concave surface, and its focal power is negative;

[0025] The object plane side of the second lens 2 is a plane, the image plane side is a convex surfa...

Abstract

The embodiment of the invention discloses an ultra-wide-field low-distortion high-pixel optical system. The optical system at least comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, and a seventh lens from an object plane to an image plane along an optical axis. In addition, the embodiment of the invention also provides a lens. The system is applied to equipment like an intelligent monitoring device or an automobile data recorder and is mainly formed by seven lenses; and because of a few of lens, the structure of the system is simple. On the basis of combination of different lenses, the system has excellent optical performances of ultra wide field, low distortion, high pixel and day-night confocal effect.

Description

Technical field: [0001] The invention relates to an optical system and a lens applied thereto, in particular to an ultra-wide-angle, low-distortion, high-pixel optical system applied to equipment such as intelligent monitoring and driving recorders, and an applied lens thereof. Background technique: [0002] Existing optical systems or lenses, especially optical systems or lenses used in equipment such as intelligent monitoring and driving recorders, have complex structures and defects. Invention content: [0003] In order to overcome the problems of existing optical systems or lenses with a large number of lenses and complex structures, embodiments of the present invention provide an ultra-wide-angle, low-distortion, and high-pixel optical system on the one hand. [0004] The ultra-wide-angle, low-distortion, and high-pixel optical system sequentially includes at least a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, and a seventh lens...
