A lens module according to the present invention comprises a first lens having a first conical surface around an optical axis and a first flat surface extending in a direction vertical to the optical axis; and a second lens having a second conical surface around the optical axis and a second flat surface extending in a direction vertical to the optical axis. The first conical surface can be connected to the first flat surface through the first curved surface of a first radius. The second conical surface can be connected to the second flat surface through the second curved surface of a second radius. |
