Abstract
The utility model relates to a day and night focusing lens, which has the function of infrared night vision. The focusing lens comprises a shell, a main cylinder that is arranged in the shell, a focus-regulating lens component, a diaphragm regulating component and a focusing lens component; the focus-regulating lens component, the diaphragm regulating component and the focusing lens component are orderly arranged on the inner side of the main cylinder in the incident direction of beams; the focus-regulating lens component is provided with four focus-regulating lenses in the incident direction of beams; the four focus-regulating lenses comprise two convex-concave lenses, a biconcave lens and a biconvex lens, which are arranged sequentially and have different mirror curvatures; the focusing lens component is provided with four focusing lenses in the incident direction of beams; the four focusing lenses orderly comprise a biconcave lens, a first biconvex lens, a second biconvex lens and a convex-concave lens, which are bonded sequentially. The day and night focusing lens can not only facilitate the realization of the function of infrared night vision, but also can acquire an ideal focal length of the lens, so that the clear and real colorful image can be seen in the day and the ideal clear image can also be seen at night. Moreover, the day and night focusing lens has the advantages of simple structure, convenient operation, and excellent effects.
Description
Technical field
The utility model relates to a kind of day and night type tight shot of tool infrared night vision function.
Background technology
Along with the development of safety monitoring industry and the raising of people's awareness of safety, 24 hours day and night continuous monitoring become a kind of trend, this trend has proposed new requirement for the research and development of CCTV camera lens, and new opportunity to develop also is provided.And therefore the infrared night vision camera lens has unlimited wide market application prospect just because of the blank of having filled up night monitoring.Owing to be subjected to technical restriction, the day and night lens of the tool infrared night vision function that performance is outstanding on the market is actually rare now.And under many circumstances, the environment of monitoring and scope are certain, therefore, design each lens parameters such as a kind of focal length and satisfy and actually require and have the day and night type tight shot of infrared night vision function again to have wide market application prospect.
Summary of the invention
The purpose of this utility model provides a kind of day and night type tight shot of tool infrared night vision function, this camera lens not only helps obtaining desirable lens focus when realizing the infrared night vision function, thereby can obtain realistic colour image clearly by day, also can obtain desirable distinct image at night, and it is simple in structure, easy and simple to handle, result of use is good.
The purpose of this utility model is achieved in that the day and night type tight shot of this tool infrared night vision function, comprise housing, the focusing lens chip module of being located at the interior main tube of housing and being located at main tube inboard along the light incident direction successively, aperture adjusting part and focusing lens assembly, described focusing lens chip module is provided with four focusing lenss, along the light incident direction, described four focusing lenss are followed successively by two different meniscuses of curvature mirror, biconcave lens and biconvex lens, described focusing lens assembly is provided with four condenser lenses, along the light incident direction, described four condenser lenses are followed successively by biconcave lens glued together and biconvex lens, biconvex lens and meniscus.
Distinguishing feature of the present utility model is that the infrared night vision technology is applied on the general tight shot, camera lens is suitable for wave band expands night-viewable scope to, realizing that camera lens has also obtained desirable lens focus in the normal imaging of 400nm～950nm wave band, make to obtain realistic colour image clearly by day, also can obtain desirable distinct image at night by this camera lens.
In addition, advantage such as that this camera lens also has is simple in structure, small volume and less weight, easy operating makes this camera lens have outstanding result of use and certain market competition advantage.
