Embodiment
It is new to this practicality below in conjunction with accompanying drawing to make the purpose of this utility model, technical scheme and advantage clearer
Each embodiment of type is explained in detail.It is however, it will be understood by those skilled in the art that each in the utility model
In embodiment, in order that reader more fully understands the application and proposes many ins and outs.But even if without these skills
Art details and many variations based on following embodiment and modification, it can also realize that each claim of the application is required and protect
The technical scheme of shield.
A kind of imaging lens are the utility model is related to, as shown in figure 1, including：Lens barrel 1, lens set 2, anti-dazzling screen 3.Wherein,
Lens barrel 1, which encloses, to be set to form a receiving space, and lens set 2 is housed in the receiving space, and anti-dazzling screen 3 is located at eyeglass in lens set 2
Image side or thing side, as shown in Fig. 2 anti-dazzling screen 3 includes：Close to thing side thing side 31, with thing side 31 with respect to and it is close
The image side surface 32 of image side, close imaging lens optical axis OO ' sides are obliquely installed and the connection of attachment side 31 and image side surface 32
Face 33.
The light injected outside from imaging lens inside lens barrel 1, its light path can pass through lens set 2 and anti-dazzling screen 3, wherein, enter
Be incident upon the thing side 31 of anti-dazzling screen 3, image side surface 32, the light on joint face 33 can be miscellaneous in being internally formed for lens barrel 1 because of reflex
Light and directly affect imaging effect, seal coat can reduce veiling glare on the thing side 31 of anti-dazzling screen 3 and image side surface 32, still
The reflex of the light to being incident on joint face 33 can not be improved, especially towards the inclined company in imaging lens optical axis OO ' directions
Junction 33, the joint face 33 can have a strong impact on imaging effect to the veiling glare reflected to form of incident light, in the present embodiment, institute
State and be all covered with carbon-coating on thing side 31, image side surface 32 and the joint face 33 of anti-dazzling screen 3, using the principle of black carbon-coating extinction,
The thing side 31 of anti-dazzling screen 3, image side surface 32, the veiling glare on joint face 33 are absorbed, thereby reduces each on anti-dazzling screen 3 be exposed to
Surface in light path, so as to effectively improve the veiling glare phenomenon inside lens barrel 1, ensure that good imaging to the reflex of light
Quality.
It is noted that in present embodiment, the lens set 2 includes at least one eyeglass.It is understood that into
As the eyeglass of the lens set 2 inside camera lens can also be 2,3,4,5 etc., specific number can be according to different demands
Selection setting is carried out, in present embodiment, using the lens set 2 with 4 lens.
In present embodiment, between the lenses, anti-dazzling screen 3 surrounds optical axis OO ' to the sandwiched of anti-dazzling screen 3 inside lens barrel 1
Set and be in hollow ring structure, the part vacated among anti-dazzling screen 3 is incident upon the imaging region of eyeglass for light.In addition, shading
The joint face 33 of piece 3 can be the surface of plane or curved surface either other shapes, specifically can be according to actual need
Ask and selected, in the present embodiment, as shown in Fig. 2 joint face 33 is plane.
In present embodiment, joint face 33 is obliquely installed towards imaging lens optical axis OO ' directions, should in present embodiment
Joint face 33 can (in practical operation, the inclined joint face 33 can also be formed by other means by being stamped and formed out
), inclined joint face 33 relative to vertical joint face 33 can be easier that veiling glare is contacted and then reflected to form with incident light.
It is understood that most of veiling glare that interference is formed to imaging effect is all to penetrate to come from the thing side direction of anti-dazzling screen 3
, in present embodiment, as shown in Fig. 2 the joint face 33 is from the thing side 31 towards the image side surface 32 along close to light
Axle OO ' direction extension, and tilted in the direction and cover carbon-coating on the joint face 33 of extension, this can be effectively absorbed from anti-dazzling screen
3 thing side directions are incident to the light on the joint face 33 of anti-dazzling screen 3, and the veiling glare for effectively preventing the direction incident forms dry to imaging effect
Disturb.
In present embodiment, the joint face 33 can also be from the thing side 31 towards the image side surface 32 along remote
Optical axis OO ' direction extension, covers carbon-coating on the joint face 33 of direction extension, can absorb other mirrors from image side direction
The veiling glare reflexed on header structure on joint face 33, veiling glare is prevented to be again reflected to the imaging region of eyeglass, so as to avoid shadow
Ring imaging effect.
It is worth noting that, the material for making anti-dazzling screen 3 has many kinds, wherein PET
(polyethylene terephthalate, PET) is a kind of thin-film material for stopping ultraviolet, its excellent optical performance,
Surfacing, bright and clean, heat endurance is good, light aging resisting, is a kind of preferably shading sheet material, so, in present embodiment, institute
The material for stating anti-dazzling screen 3 is PET.
In addition, the imaging lens can also include shadow shield 4, the collecting that the shadow shield 4 is housed in the formation of lens barrel 1 is empty
In, and be disposed adjacent with the anti-dazzling screen 3, specifically, as shown in figure 1, shadow shield 4 is located in the lens set 2 most
Between two adjacent mirrors of image side, shadow shield 4 contacts setting close to two surfaces of image side, thing side with anti-dazzling screen 3.Can
With understanding, shadow shield 4 can also be placed in the other positions in lens barrel 1.The function phase of the shadow shield 4 and anti-dazzling screen 3
It is similar, all with certain interception.
In present embodiment, the imaging lens can also include pressure ring 5, and the pressure ring 5 is by the lens set 2 and sandwiched
The structures such as the anti-dazzling screen 3 in lens set 2 are fixed in the receiving space, to play firm make to the structure inside whole camera lens
With.The inwall of the pressure ring 5 and lens barrel 1 is connected, specifically, the pressure ring 5 can be realized by way of viscose glue and mirror
The inwall of cylinder 1 is connected or is attached otherwise, for example is interference fitted, and in the inwall corresponding position of lens barrel 1
It may be provided with the outward flange that link slot carrys out clamping pressure ring 5；In addition, the pressure ring 5 can be metal pressure ring or plastic cement pressure
Ring.In present embodiment, the pressure ring 5 used is connected for plastic cement pressure ring by viscose glue mode with the inwall of lens barrel 1.
It will be understood by those skilled in the art that the respective embodiments described above are to realize specific implementation of the present utility model
Example, and in actual applications, can to it, various changes can be made in the form and details, without departing from spirit of the present utility model
