LENS AND LENS MODULE INCLUDING THE SAME
The present disclosure relate to the field of optical imaging technologies, and discloses a lens and a lens module including the same. The lens includes: an optical portion located at a central position; a bearing portion surrounding the optical portion; and a reinforcing portion embedded in the bearing portion and configured to reinforce the bearing portion. The reinforcing portion is annular. The bearing portion includes an object-side surface close to an object side and an image-side surface opposite to the object-side surface. The reinforcing portion is located between the object-side surface and the image-side surface in a direction parallel with an optical axis. The lens and the lens module including the lens provided by the present disclosure can enhance the ability to resist deformation of the lens, thereby improving the yield of the lens module.
1 . A lens, comprising:
an optical portion located at a central position;
a bearing portion surrounding the optical portion; and
a reinforcing portion embedded in the bearing portion and configured to reinforce the bearing portion,
wherein the reinforcing portion is annular; the bearing portion comprises an object-side surface close to an object side and an image-side surface opposite to the object-side surface;
and the reinforcing portion is located between the object-side surface and the image-side surface in a direction parallel with an optical axis.
2 . The lens as described in claim 1 , wherein the bearing portion further comprises a peripheral surface connecting the object-side surface with the image-side surface, a recessed portion recessed from the peripheral surface towards the optical axis is provided on the bearing portion; and the reinforcing portion is fixed in the recessed portion.
3 . The lens as described in claim 2 , wherein the reinforcing portion comprises a first surface, a second surface, an inner side surface and an outer side surface; the first surface and the second surface are opposite to each other in a direction of the optical axis; the inner side surface and the outer side surface connect the first surface with the second surface; and the outer side surface is recessed from the peripheral surface towards the optical axis.
4 . The lens as described in claim 3 , wherein the reinforcing portion has equal distances to the object-side surface and the image-side surface in a direction parallel with the optical axis.
5 . The lens as described in claim 1 , wherein the reinforcing portion is made of a metal material.
6 . The lens as described in claim 5 , wherein the bearing portion and the reinforcing portion are formed into one piece.
7 . A lens module, comprising the lens as described in claim 1 .
8 . A lens module, comprising the lens as described in claim 2 .
9 . The lens module as described in claim 7 , further comprising:
a lens barrel having a receiving space; and
an optical assembly received in the receiving space,
wherein the optical assembly comprises a first lens close to the object side, a second lens provided at an image side of the first lens, a light-blocking plate provided at an image side of the second lens, a fourth lens provided at an image side of the light-blocking plate, and the lens provided between the second lens and the light-blocking plate.
