Abstract
A camera module includes a lens barrel, a first lens and a second lens. The lens barrel includes a substantially cylindrical inner wall. The first lens is received in the lens barrel. The first lens includes a first circumferential side surface spaced from the inner wall. The second lens is engaged with the first lens and received in the lens barrel. The second lens includes a second circumferential side surface. The second circumferential side surface has a first portion contacting the inner wall and a second portion spaced from the inner wall, thus a gap defined between the second portion and the inner wall. Adhesive is applied in the gap between the second portion and the inner wall.
Claims14
A camera module, comprising:
- a lens barrel comprising a substantially cylindrical inner wall and a flange extending inward from the inner wall at a first end of the inner wall;
- a first lens disposed in the lens barrel, and comprising a first optical portion and a first fixing portion surrounding the first optical portion, the first fixing portion comprising a first object-side surface contacting the flange, an opposite first image-side surface, and a first side surface between the first object-side surface and the first image-side surface;
- a second lens received in the lens barrel, and comprising a second optical portion and a second fixing portion surrounding the second optical portion, the second fixing portion comprising a second object-side surface engaging with the first image-side surface of the first lens, an opposite second image-side surface and a second side surface between the second object-side surface and the second image-side surface, the second side surface of the second lens comprising a first portion adjacent to the flange and a second portion away from the flange, the first portion tightly abutting the inner wall, the second portion spaced a distance from the inner wall to form a filling space therebetween, an annular groove being defined at a periphery portion of the second image-side surface of the second lens, the annular groove communicating with the filling space;
- and
- adhesive applied in the filling space between the second portion and the inner wall.
