Abstract
In a lens module, a concave portion may be formed on an image-side surface of a first lens, a convex portion protruding toward the concave portion may be formed on an object-side surface of a second lens, an outer region of the concave portion of the first lens and an outer region of the convex portion of the second lens may be closely adhered to each other, the concave portion and the convex portion may be spaced apart from each other, and a gap between the concave portion and the convex portion in an optical axis direction and a gap between the concave portion and the convex portion in a direction perpendicular to an optical axis may be formed so as to be different from each other.
Claims14
A lens module comprising:
- a first lens having a concave portion formed on an image-side surface thereof;
- and
- a second lens having a convex portion formed on an object-side surface thereof and protruding toward the concave portion,
- wherein the first and second lenses are closely adhered to each other at outer regions of the concave portion and the convex portion and the concave portion and the convex portion are spaced apart from each other, and
- a gap between the concave portion and the convex portion in an optical axis direction and a gap between the concave portion and the convex portion in a direction perpendicular to an optical axis are different from each other.
A lens module comprising:
- a first lens having a first conical surface, a first inner horizontal surface, and a first outer horizontal surface formed on an image-side surface thereof, the first conical surface being inclined and the first inner horizontal surface and the first outer horizontal surface being formed on both sides of the first conical surface, respectively;
- and
- a second lens stacked together with and assembled with the first lens in an optical axis direction and having a second conical surface, a second inner horizontal surface, and a second outer horizontal surface formed on an object-side surface thereof facing the image-side surface of the first lens, the second conical surface being inclined and the second inner horizontal surface and the second outer horizontal surface being formed on both sides of the second conical surface, respectively,
- wherein the first and second inner horizontal surfaces are spaced apart from each other to form a first air gap,
- the first and second conical surfaces are spaced apart from each other to form a second air gap, and
- the first air gap is larger than the second air gap.
