CAMERA MODULE AND VEHICLE COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2022/235108
Kind Code:
A1
Abstract:
A camera module disclosed in an embodiment of the present invention comprises a lens barrel having a through-hole formed therein; and a first lens, a second lens, and a third lens which are coupled to the through-hole of the lens barrel and having optical axes arranged from an object side toward a sensor side, wherein a material of the second lens is different from a material of the first lens, the refractive index of the second lens is less than the refractive index of the first lens, and the second lens includes a flange portion extending from the optical axis toward the inner surface of the lens barrel. The length of a first contact surface where the flange portion of the second lens is in contact with the inner surface of the lens barrel is 20% to 50% of the thickness of the flange portion. In the second lens, a third surface at the object side and a fourth surface at the sensor side have different radiuses of curvature from each other. The center of the first contact surface wherein the flange portion of the second lens is in contact with the inner surface of the lens barrel can be located adjacent to, on the basis of the center in the thickness of the flange portion, one having greater radius of curvature between the third and fourth surfaces.
