Camera lens assembly
View Patent ↗A camera lens includes a barrel, a first lens, a second lens and an optical filter module. The barrel includes a first container and a diaphragm. The first lens is disposed in the first container next to the diaphragm. The second lens is disposed in the first container with a distance from the first lens. The optical filter module is disposed in the first container between the first and the second lenses.
1. A camera lens assembly, comprising:
a barrel, which has a first container and a diaphragm;
a first lens, which is accommodated in the first container and is next to the diaphragm;
a second lens, which is accommodated in the first container, wherein an interval is disposed between the first lens and the second lens; and
an optical filter module, which is accommodated in the first container and is located between the first lens and the second lens.
2. The camera lens assembly of claim 1 , wherein the optical filter module comprises a spacer and a filter.
3. The camera lens assembly of claim 2 , wherein the filter is an infrared rays filter (IR filter).
4. The camera lens assembly of claim 2 , wherein the spacer has a second container, and the filter is accommodated in the second container.
5. The camera lens assembly of claim 1 ; wherein the first lens is an aspherical lens.
6. The camera lens assembly of claim 1 , wherein the first lens is a plastic lens.
7. The camera lens assembly of claim 1 , wherein the second lens is an aspherical lens.
8. The camera lens assembly of claim 1 , wherein the second lens is a plastic lens.
9. The camera lens assembly of claim 1 , wherein the first lens has a convex surface next to the diaphragm.
10. The camera lens assembly of claim 1 , wherein the second lens has a surface next to the optical filter module and an anticlastic surface opposite to the surface.
11. The camera lens assembly of claim 1 , wherein the thickness of the optical filter module is approximately equal to the interval between the first lens and the second lens.
12. The camera lend assembly of claim 1 , further comprising a holder.
13. The camera lens assembly of claim 12 , wherein the barrel is connected to the holder.
14. The camera lens assembly of claim 1 , further comprising:
