Lens group of imaging system

Abstract

The invention provides a lens group of an imaging system, which comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens, wherein the first lens, the second lens, the third lens, the fourth lens, the fifth lens and the sixth lens are sequentially arranged from an object side to an image side; the third lens and the fourth lens form a glued assembly; and thefifth lens and the sixth lens form a glued assembly. The lens group can provide an imaging quality with high resolution and low aberration.

Description

technical field [0001] The invention relates to an imaging system lens group. Background technique [0002] Optical imaging systems, especially refractive optical imaging systems, often require an optical imaging lens to receive imaging light reflected by an imaging object for imaging. However, optical imaging lenses usually have unfavorable factors such as spherical aberration, coma aberration, astigmatism, curvature of field, and distortion. Therefore, improving optical imaging quality and providing high-pixel, low-aberration imaging are always the same for optical imaging systems. requirements. For example, cameras used in monitoring systems or vehicle systems need to provide clear and accurate images for user reference. With the development of science and technology and technological progress, various technical fields related to optical imaging, such as vehicle-mounted optical imaging systems used in the automotive industry, mobile electronic devices such as camera equ...
