First Claim
Patent Images
1. An optical lens, comprising:
- a barrel comprising a light incidence opening and a receiving space, wherein the receiving space is connected with the light incidence opening;
a first lens, disposed in the receiving space, wherein the first lens comprises a first outer loop and at least one protrusion, wherein the protrusion is disposed on the first outer loop, and a portion of the first lens is exposed by the light incidence opening;
a second lens, disposed in the receiving space and lodged to the first lens, wherein the second lens comprises a second outer loop and at least one recess, wherein the recess is disposed on the second outer loop, the first outer loop is leant on the second outer loop, and the protrusion is lodged to the recess; and
a baffle, disposed between the first lens and the second lens.

Abstract
A lens system including a first lens and a second lens is provided. The first lens has a first outer loop and at least a protrusiondisposed on the first outer loop of the first lens. In addition, the second lens is lodged to the first lens. The second lens has a second outer loop and at least a recess disposed on the second outer loop of the second lens. The first outer loop is leant to the second outer loop, and the protrusion is lodged to the recess. Accordingly, the first lens and the second lens have an excellent alignment precision.
