Description
Technical field
The utility model relates to a kind of camera lens, in particular to a kind of camera lens with night vision function.
Background technique
With the development of the times with progress, video camera is gradually widely used.Video camera it is many kinds of, but it is all
Camera operation principle is the same；Optical image signal is changed into electric signal, in order to store or transmit.When us
When shooting an object, the light reflected on this object is collected by camera lens, focuses on it on light-receiving surface of picture pick-up device,
Light is changed into get " vision signal " has been arrived by picture pick-up device by electric energy again.Obtained standard signal is finally transmitted to record
It is recorded on the recording mediums such as camera, or propagates or be sent on monitor by broadcasting system and show.
Although video camera has been widely used, existing video camera can not accomplish that anthropoid eyes are the same, clearly
The clear things that will be seen that shows, while having big wide-angle view, and most of video cameras are without night vision function, Wu Fa
It is used under dark surrounds.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of video camera mirror with night vision function
Head not only has night vision function, and has excellent resolution ratio and ultra wide-angle, can effectively reduce optical distortion, whole
It is light-weight.
The technical solution of the utility model is as follows:
A kind of camera lens with night vision function, the lens barrel including the hollow structure with upper and lower opening, the mirror
The inside of cylinder is disposed with aspherical protection face mirror, the first plastic lens, optically focused channel, the second plastic rubber mirror from the object side to the image side
Piece and colour filter, between the circumference of the aspherical protection face mirror and the inner sidewall of the lens barrel and first plastic lens
It is provided with washer, the exit facet of first plastic lens passes through the plane of incidence in the optically focused channel and second plastic lens
It is connected, the exit facet of second plastic lens is connect with the colour filter, is provided with mirror at the object space side opening of the lens barrel
Focusing ring is arranged in head, the circumference of the camera lens, and the circumference of the focusing ring is arranged infrared tabula rasa, uniformly sets on the infrared tabula rasa
Several LED light are equipped with, focusing ring is arranged in the circumference of the infrared tabula rasa.
Further, the plane of incidence of the exit facet of first plastic lens and second plastic lens is to be oppositely arranged
Arc convex.
Further, first plastic lens, optically focused channel, be provided with cushion block between the second plastic lens.
Further, the lens barrel is plastic cement antidetonation lens barrel.
Further, the circumference of the focusing ring is equipped with anti-skid chequer.
Compared with the existing technology, the utility model has the beneficial effects that:
According to optical Design, aspherical protection face mirror assumes responsibility for the larger focal power of entire optical lens system, makes axis
After preceding group of eyeglass, the angle of light and optical axis is quickly reduced outer light beam, total with rear group of eyeglass due to using aspherical face type
The camera lens is used so that realizing has excellent resolution ratio within the scope of the full filed of optical lens system with correction off-axis aberration
The photo taken, visual angle can reach 145 degree or more, and because of the setting of the first plastic lens and the second plastic lens, can be effective
Reduce optical distortion within 22%, reduce overall weight.
Aspherical protection face mirror also provides a protective effect, the setting of circumference washer and external plastic cement antidetonation lens barrel
Under effect, shock resistance with super strength further protects camera lens, extends service life.
3, the function that night vision is realized by infrared light board realizes the function of enhancing light by LED light, realizes without striation
Shooting under part increases the practical of video camera, guarantees that the shooting of camera is clear for focusing by setting focusing ring
Clear degree and shooting effect.
Detailed description of the invention
Fig. 1 is the overall structure main view of the utility model；
Fig. 2 is the overall structure cross-sectional view of the utility model.
