Document Type and Number:
WIPO Patent Application WO/2022/188561
Kind Code:
A1
Abstract:
A multispectral camera lens (1), a multispectral optical system (3) and a multispectral camera (2). The camera lens (1) comprises a housing (10), a first lens set (21), a second lens set (22) and an aperture assembly (30), wherein the housing (10) is in the shape of a cylinder having a hollow cavity; the first lens set (21) and the second lens set (22) are mounted in the hollow cavity, the first lens set (21) is mounted on an object-space side of the housing (10), and the second lens set (22) is mounted on an image-space side of the housing (10); and the aperture assembly (30) is mounted between the first lens set (21) and the second lens set (22), and after being transmitted through the first lens set (21), light rays pass through the aperture assembly (30) to reach the second lens set (22). The aperture assembly (30) comprises a first aperture used for transmitting light rays in a first wavelength range, and a second aperture used for transmitting light rays in a second wavelength range, wherein the first aperture and the second aperture are formed in the same plane, a wavelength in the first wavelength range is greater than a wavelength in the second wavelength range, and the area of the first aperture is smaller than the area of the second aperture.
