Benefits of technology

In this new technology, there were technical improvements that improved image resolution over traditional methods such as zoom or pan shading techniques. These technologies resulted in smaller cameras being able to capture images at different temperatures without losing their sharpness due to changes made during manufacturing processes. Additionally, these innovations aim towards reducing costs compared to older systems like those based on liquid crystal display (LCD) screens. Overall, they improve camera performance and reduce production time.

Problems solved by technology

This patented technology has limitations with regards to image quality due to its size and thickness that make it difficult to achieve high levels of accuracy over long distances without losing resolution during use on vehicles. Additionally, existing solutions like curved mirrors can cause issues if they get bent by road conditions causing glare effects at certain angles.

Embodiment Construction

[0023] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0024] A kind of small optical lens, in the cavity of lens barrel 1, be provided with first lens 2, second lens 3, third lens 4 and fourth lens 5 and optical filter 6 successively, described first lens 2 The material of the spherical lens is LASF015 optical glass; the material of the third lens 4 is ZF17 optical glass; the material of the second lens 3 and the fourth lens 5 is F4520 optical plastic. This optical filter 6 is fixed in the cavity of lens barrel 1, and the below of optical filter 6 is exactly CCD photosensitive chip, and light enters from optical filter 6, and optical filter 6 has certain protective effect to CCD photosensitive chip, simultaneously Part of the light is also filtered to make the image bright and sharp while having good color reproduction. In addition to solving the problem of color, the filter 6 also ensures the smoo...

Abstract

The invention discloses a small optical lens. A first lens, a second lens, a third lens, a fourth lens, and an optical filter are sequentially arranged in a cavity of a lens cone; the first lens is a crescent spherical lens; the second lens is a crescent plastic aspheric lens with capacity of reducing distortion; the third lens is a drum-shaped spherical lens and the fourth lens is a drum-shaped plastic aspheric lens; the curvature radii of the front and rear surfaces of the first lens which is the crescent spherical lens are 13.5mm and 2.9mm respectively; and the curvature radii of the front and rear surfaces of the third lens are 2.9mm and -13.4mm respectively. The small optical lens is a small low-distortion optical lens which is mainly applied to monitoring and vehicle-mounted occasions.
