However, the smaller the light-transmitting part, the larger the mounting part needs to be supported. Although the larger mounting part is helpful for the stability of the lens assembly, it will also make the glare more serious

Abstract

The invention relates to a space ring (1) and a lens. The space ring (1) comprises an annular body (11), and the outer side of the annular body (11) separately extends towards an object side and an image side along an optical axis to form a first bearing part (12) and a second bearing part (13). With the space ring of the invention adopted, the assembly stability of the lens can be remarkably improved, and dazzle light can be effectively weakened.

Description

technical field [0001] The invention relates to the technical field of optical elements, in particular to a spacer and a lens. Background technique [0002] With the continuous improvement of consumers' requirements for mobile phone photography, wide-field and large-format imaging effects are becoming more and more important, and wide-angle lenses can perfectly meet the above requirements. Therefore, wide-angle lenses have made great progress, and their field of view has evolved from 85° to more than 120°. However, as the field of view increases, the chromatic aberration of the lens becomes more and more difficult to control. It is necessary to design a central diaphragm to effectively control the optical chromatic aberration. For this lens structure, when the light passes through the lens structure with a central diaphragm, the path the light passes through is basically a "V" shape after being refracted by the lens group, which means that the lens in the middle of the lens...
