Abstract
The invention discloses a CCD (Charge Coupled Device) gain lens, comprising a shell and a lens assembly arranged in the shell. The lens assembly comprises a cambered surface lens, a first plane lens, a spherical lens and a second plane lens in sequence from a light incoming end to a light outgoing end. The recessed surface of the cambered surface lens is opposite to the light incoming end. The shell is of a hollow structure and of a cone structure. An end part, close to the light incoming end, of the shell is a small end, and the other end part, close to the light outgoing end, of the shell is a large end. The cambered surface lens, the first plane lens, the spherical lens and the second plane lens are matched with the shell. With the abovementioned structure, the lens assembly is cooperated with the shell, light beams at the light incoming end are subjected to focusing, thereby improving the definition of the CCD shooting image.
Description
Technical field
The present invention relates to a kind of CCD gain camera lens, particularly relate to a kind of result of use good, focus on obvious CCD gain camera lens.
Background technology
The appearance of ccd video camera and development, for safety precaution provides a kind of brand-new technological means, because it not only has eye-catching deterrent effect, and strong evidence can be provided for solving a case, thus every field is widely used in, as played very important effect in cctv surveillance.Ccd video camera is positioned at the forefront of closed-circuit TV monitoring system, can be described as " eyes " of whole system, and its quality will affect the quality of whole system.For ccd video camera, the most key with CCD camera lens, its image quality will dominate the quality of ccd video camera.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of CCD gain camera lens, have result of use good, focus on obvious feature.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of CCD gain camera lens, comprise housing and be arranged on lens combination in described housing, its innovative point is: described lens combination is followed successively by lens curve, the first planar lens, spherical lens, the second planar lens from light inputting end to bright dipping end, and the concave surface of lens curve is relative with light inputting end; Described housing is hollow structure and in cone structure, the shell end near light inputting end is small end, and be large end near housing the other end of bright dipping end, described lens curve, the first planar lens, spherical lens, the second planar lens and described housing match.
Preferably, the face of described spherical lens and described body contact is plane.
Preferably, the face that described first planar lens and described lens curve face is provided with the first concave surface.
Preferably, described first concave surface is positioned at the center of described first planar lens, and the area of described first concave surface is less than the area of described first planar lens.
Preferably, described second planar lens is convex surface near bright dipping end side.
Preferably, described housing is cylindrical structure or rectangular structure.
The invention has the advantages that: by adopting said structure, utilize coordinating of lens combination and housing, the light beam of light inputting end being carried out focusings process, thus the high definition of raising CCD shooting image quality.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
Fig. 1 is the structural representation of a kind of CCD gain of the present invention camera lens.
