Document Type and Number:
WIPO Patent Application WO/2021/261615
Kind Code:
A1
Abstract:
The present invention relates to an imaging lens, and a camera module and an electronic device comprising same. An imaging lens according to one embodiment of the present invention comprises: a catadioptric lens through which light is incident from an object side and from which the light exits by being reflected from the inside thereof; and a lens group including a plurality of lenses that transmit the light emitted from the catadioptric lens to an image plane, wherein the catadioptric lens comprises: an incident surface on which the light is incident from the object side; a second mirror surface that is concave toward the object side and reflects the light incident from the incident surface to a first mirror surface of the object side; the first mirror surface that is convex toward the image plane in the central portion of the incident surface and reflects the light reflected from the second mirror surface toward the image side; and an exit surface through which the light reflected from the first mirror surface exits, and wherein the lens group may be disposed between the first mirror surface and the second mirror surface with respect to an optical axis. Accordingly, it is possible to increase the brightness of the lens, increase the resolution, suppress an increase in thickness, and reduce an assembly tolerance of a mirror.
