Abstract
A lens module includes a lens barrel, a lens and an aperture plate. The lens barrel includes a main body. The lens barrel includes a main body with an inner sidewall. The lens is received in the main body and includes an optical portion and a non-optical portion surrounded the optical portion. The aperture plate is disposed on the image-side surface of the non-optical portion of lens. The aperture plate defines a plurality of cutouts on the outer periphery thereof and thereby leaving a plurality of flanges at the outer periphery thereof. The flanges abut the inner side wall. The cutouts are coated adhesive to firmly attach the aperture plate on the image-side surface of the lens and fixed on the inner sidewall of the main body.
Claims4
A lens module comprising:
- a lens barrel comprising a main body with an inner sidewall;
- a lens received in the main body and comprising an optical portion and a non-optical portion surrounding the optical portion;
- an aperture plate disposed on the image-side surface of the non-optical portion of the lens, the aperture plate defining a plurality of cutouts in an outer periphery thereof, the outer periphery abutting the inner sidewall of the main body, the cutouts opposite to the inner sidewall of the main body;
- an adhesive applied in the cutouts to firmly attach the aperture plate on the image-side surface of the non-optical portion of the lens and fixed on the inner sidewall of the main body;
- wherein the lens barrel comprises an annular aperture plate positioned at the object-side end of the main body, the annular aperture plate defines an aperture opening generally at the center thereof, the aperture opening tapers towards the image-side of the lens barrel.
A lens module, comprising:
- a lens barrel comprising a main body and an annular aperture plate positioned at the object-side end of the main body, the main body comprising an inner sidewall;
- a first lens mounted on the inner sidewall of the main body, and comprising an optical portion and a non-optical portion surrounding the optical portion;
- a second lens mounted on an image-side surface of the first lens and comprising an optical portion and a non-optical portion surrounding the optical portion;
- an opaque plate sandwiched between the first lens and the second lens;
- an aperture plate disposed on the image-side surface of the non-optical portion of the second lens, the aperture plate defining a plurality of cutouts in an outer periphery thereof, the outer periphery abutting the inner-sidewall of the main body, the cutouts opposite to the inner sidewall of the main body;
- and
- an adhesive applied in the cutouts to firmly attach the aperture plate on the image-side surface of the non-optical portion of the second lens and fixed on the inner sidewall of the main body;
- wherein the image-side surface of the non-optical portion of the first lens defines two recesses, two second locating portions extend from the object-side surface of the non-optical portion of the second lens engaged in the respective recess.
