AI Technical Summary
Technical Problem
When recording the scene, the camera of the law enforcement recorder may produce unclear images or have a small field of view, making it unable to record a large area of the scene.
Method used
It employs an eight-lens structure with specific optical power and surface shape design, including a combination of negative and positive optical power lenses, to meet specific focal length ratio and radius of curvature conditions. Combined with aperture and filter, it optimizes the total optical length and field of view.
Benefits of technology
It achieves optical lenses with a large field of view, large aperture, miniaturization, and high imaging quality, reducing aberrations and distortion, and improving image quality.

Abstract
This invention provides an optical lens composed of eight lenses, arranged sequentially along the optical axis from the object side to the image plane: a first lens with negative optical power, its object side being convex and its image side being concave; a second lens with negative optical power; a third lens with negative optical power, its object side being concave; a fourth lens with positive optical power, its object side being convex and its image side being concave; a fifth lens with positive optical power, its object side being convex and its image side being convex; a sixth lens with negative optical power, its object side being concave and its image side being convex; a seventh lens with negative optical power; and an eighth lens with positive optical power, its object side being convex and its image side being concave. The optical lens provided by this invention can reduce aberrations, improve image quality, and give the lens one or more advantages such as a large field of view, a large aperture, miniaturization, and high image quality.
