Further, described first lens bore diameter is greater than described second lens opening, and described second lens bore diameter is greater than described 3rd lens opening.
Further, described first plano-convex lens and described first space ring are arranged in described first lens opening, described second plano-convex lens, the second space ring, the 3rd plano-convex lens and the 3rd space ring are arranged in described second lens opening, and the first biconvex lens, the 4th space ring, the second biconvex lens, the 5th space ring, the first plano-concave lens and the 4th plano-convex lens are arranged in described 3rd lens opening.
Further, described 3rd plano-convex lens bottom surface scribbles a circle shading coating.
Further, described 3rd space ring is provided with lens groove, and the diameter of described lens groove is identical with the diameter of described first biconvex lens.
Further, described second cylindrical shell is also provided with connecting thread outward.
The beneficial effects of the utility model: camera lens of the present utility model is primarily of mirror cap, lens barrel and interior lens composition, and structure is simple, and interior lens interval is compact, rationally distributed, so camera lens volume is little; The multiple lens of inner employing match in addition, make lens imaging clear, the situation in the gem-pure observation ear of energy.
