Title:
LENS MODULE AND IMAGING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/000258
Kind Code:
A1
Abstract:
Disclosed are a lens module (100) and an imaging system. The lens module comprises a lens cone (1) and a plurality of lenses (2) accommodated in the lens cone (1), wherein the plurality of lenses (2) are sequentially arranged at intervals in the direction of the optical axis (00') of the lens cone (1), and at least one of the plurality of lenses (2) is a glass lens (2). By means of providing at least one invisible light cut-off film (3) on any one of an object side face (21) and image side face (22) of the glass lens (2), the imaging system can directly cut off invisible light, such as infrared light, outside an imaging area by means of the glass lens (2), without needing to add an additional light filter in front of an electronic image sensor, so as to avoid interference to visible light imaging, thereby reducing the length of the imaging system and the height of the lens module (100), and realizing a more compact overall structure; at the same time, the number of optical faces between the lens module (100) and the electronic image sensor is reduced, and the subjective experience and feeling of photography is better.
