1. A lens module, having an optic axis and comprising:
a lens holder having a first holder and a second holder extending vertically from an edge of the first holder, the first holder having a top surface perpendicular to the optic axis, a bottom surface opposed to and parallel to the top surface, and a first inner surface parallel to the optic axis and connecting the top surface to the bottom surface, the second holder having a second inner surface perpendicular to and jointing with the bottom surface of the first holder; a receiving space formed by the bottom surface and the second inner surface; a lens unit accommodated in the receiving space, the lens unit comprising:
a first lens having a first object-side surface, a first image-side surface, and a side surface connecting the first object-side surface to the first image-side surface, the side surface abutting against the second inner surface of the second holder;a second lens having a second object-side surface, a second image-side surface, and a jointing surface connecting the second object-side surface to the second image-side surface, the jointing surface keeping a distance from the second inner surface of the second holder;the first object-side surface comprising a first plane abutting against the bottom surface of the first holder;the first image-side surface comprising a second plane parallel to the first plane, a first arc surface connecting the second plane, and a third plane connecting with the first arc surface and parallel to the second plane;the second object-side surface comprising a first carrying surface abutting against the second plane, a second arc surface abutting against the first arc surface, and a second carrying surface keeping a distance from the third plane. |
