Title:
LENS UNIT, CAMERA MODULE, IMAGING SYSTEM, AND MOVING BODY
Document Type and Number:
WIPO Patent Application WO/2024/014106
Kind Code:
A1
Abstract:
Provided are a lens unit in which play that occurs in a lens can be suppressed and a prescribed inter-surface sensitivity can be ensured, a camera module, an imaging system, and a moving body. A middle wall 26 having a light passage hole 25 that is orthogonal to an optical axis and through which light passes is provided between an object-side end of a lens barrel 12 and an image-side end thereof, lenses 13, 14, 15 are inserted from the object-side end of the lens barrel 12 closer to the object side than the middle wall 26, lenses 16, 17 are inserted from the image-side end of the lens barrel 12 closer to the image side than the middle wall 26, the lenses 14, 15, 16 for which an inter-surface sensitivity, which is the sensitivity of image formation with respect to a lens inter-surface distance, becomes a high inter-surface sensitivity higher than the inter-surface sensitivity between the other lenses are contacted by the middle wall 26, and the optical axis direction of the lenses 14, 15, 16 is thereby positioned.
