Title:
OPTICAL IMAGING LENS GROUP AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/082627
Kind Code:
A1
Abstract:
An optical imaging lens group and the use thereof, relating to the technical field of display imaging. By defining the working distance of an optical imaging lens group and limiting a numerical range, and by defining Y1, Y2 and Y3 and limiting the proportional relation of Y1, Y2 and Y3, the optical imaging lens group consisting of a plurality of lenses can produce a clear image of a curved surface image at a second side, so that the curved surface image can be quickly and accurately matched during installation and adjustment of the optical imaging lens group. The present application not only can produce the high-quality clear image of the curved surface image at the image side, but also helps to reduce the assembly process difficulty of the whole optical imaging lens group and to implement mass assembly production at low cost, laying a good technical foundation for machining and quality control of products comprising the optical imaging lens groups.
