Abstract
It the utility model is related to a kind of axis light copolymerization zoom lens that can effectively eliminate veiling glare to disappear veiling glare device, including copolymerization zoom lens, inside, leading portion or the rear end of camera lens are provided with one piece of diaphragm in the copolymerization zoom lens；The centre of the diaphragm is shading region, is all around transparent area.Advantage：The axis light copolymerization zoom lens veiling glare device that disappears makes large scale veiling glare not return by setting up diaphragm to connect sensitive area, and then very limited to blocking for effective light, so as to significantly lift the ratio that receives of effective light, realizes the lifting of observing effect and the signal degree of accuracy.
Description
Technical field
It the utility model is related to a kind of axis light copolymerization zoom lens that can effectively eliminate veiling glare to disappear veiling glare device, belong to same
Axle light is copolymerized zoom lens manufacturing field.
Background technology
Existing small field of view axis light copolymerization zoom lens mainly have three types：The first kind is as shown in figure 1, on the left of aperture A
Light source illuminate aperture A, the light through aperture A focuses on B location through camera lens C, and B location is irradiated to when B location has object
Light sequentially pass through camera lens C and aperture A to the left through object reflection, and leading sensor by optical system measures sensor
Signal.Second class as shown in Fig. 2 light from incident optical enter and from incident optical and receive optical fiber merge end A ' injection, wear
Cross incident optical and merge end A ' light with receiving optical fiber and focus on B location through camera lens C, B positions are irradiated to when B location has object
The light put sequentially passes through camera lens C through object reflection and merges end A ' with receiving optical fiber through incident optical to the left, then by connecing
By optical fiber sending out signals, leading sensor finally by optical system makes sensor measure signal.3rd class is as shown in figure 3, mirror
Half-reflecting mirror D is provided with head C or before and after it, A ' ' in figure（A ' ' is that aperture or incident optical merge end with receiving optical fiber）With
A’’’（A ' ' ' is light source）Optically mirror image, the light sent from A ' ' ' focus on and half-reflecting mirror D reflections through camera lens C each other
Gather at B points, the light that B location is irradiated to when B location has object passes through camera lens C and half-reflecting mirror D to the left through object reflection
Gather A ' ', and leading sensor by optical system makes sensor measure signal.Due to the limitation of manufacturing process, composition focuses on
Certain reflectivity, the small field of view axis light copolymerization zoom lens of above-mentioned three types, luminous point A/ be present in the lens surface of camera lens
The light that A '/A ' ' ' is sent is partially reflected back to by the optical lens surface in camera lens first during through amasthenic lens
A/ A '/A ' ' is simultaneously passed through, and forms background miscellaneous light, especially in the case where the object reflectance of B location is very low, effective signal
Even it is weaker than signal caused by veiling glare, has a strong impact on observation and signal order of accuarcy.
Utility model content
Purpose of design：The weak point in background technology is avoided, a kind of axis light that can effectively eliminate veiling glare is designed and is total to
Amasthenic lens disappears veiling glare device.
Design：In order to realize above-mentioned purpose of design.The utility model is in structure design：1st, it is copolymerized mirror in zoom lens
Inside, front end or the rear end of head are provided with the design of one piece of diaphragm, are one of the technical characteristics of the utility model.The mesh so designed
Be：Because inside, front end or the rear end of camera lens in copolymerization zoom lens are provided with one piece of diaphragm, it is thus possible to greatly reduce coaxial
Light copolymerization zoom lens disappear the space-consuming of veiling glare device.2nd, the centre for stating diaphragm is shading region, is all around the design of transparent area,
It is the two of the technical characteristics of the utility model.The purpose so designed is：When the centre of diaphragm is shading region, is all around
During light area, because the veiling glare of veiling glare large scale is all to return to connect sensitive area from the scope for receiving light region fore very little angle, institute
Can wholly or largely it be covered by diaphragm with returning to out the veiling glare of small range near incidence hole or optical fiber merging end and full filed, and
And can effectively light block it is then very limited so that the ratio of effective light greatly promotes, so as to considerably increase observing effect and
The signal degree of accuracy.3rd, diaphragm is made of metal, or is made up of light transmissive material of the surface with light-shielding pattern, or among light transmissive material
Light-proof material is inlayed to be made.It is the three of the technical characteristics of the utility model.The purpose so designed is：When diaphragm is by metal
When being made, or when being made up of surface with the light transmissive material of light-shielding pattern, or light-proof material is inlayed among light transmissive material and is made
When, its diaphragm impurity elimination light effect is optimal, disappears the impurity elimination light effect of veiling glare device so as to improve axis light copolymerization zoom lens.
Technical scheme：A kind of axis light copolymerization zoom lens disappear veiling glare device, including copolymerization zoom lens, the copolymerization zoom lens
Inside, leading portion or the rear end of middle camera lens are provided with one piece of diaphragm；The centre of the diaphragm is shading region, is all around transparent area.
Compared with background technology, the axis light copolymerization zoom lens veiling glare device that disappears makes to compare greatly the utility model by setting up diaphragm
Example veiling glare veiling glare, which can not return to, connects sensitive area, and then very limited to blocking for effective light, so as to significantly lift effective light
The lifting for receiving ratio, realizing observing effect and the signal degree of accuracy.

Embodiment
Embodiment 1：Referring to the drawings 4-7.A kind of axis light copolymerization zoom lens disappear veiling glare device, including copolymerization zoom lens 1,
Visual field is small area side or bowlder, and the inside for being copolymerized camera lens 2 in zoom lens 1 is provided with one piece of diaphragm 4, and the camera lens 2 is by extremely
Few two pieces of eyeglasses 21 are formed, and diaphragm 4 is located therein between two pieces of adjacent eyeglasses 21, or in copolymerization zoom lens 1 camera lens 2 with going out
Unthreaded hole or incident optical are provided with one piece of diaphragm 4 with receiving between optical fiber merges end 3；The centre of the diaphragm 4 is shading region, all around
For transparent area, both 4 middle small area of diaphragm was blocked and a wide range of printing opacity of surrounding.The diaphragm 4 is made of metal, or by surface band
The light transmissive material for having light-shielding pattern is made, or light-proof material is inlayed among light transmissive material and is made.
If visual field is wire（Equivalent to multiple small area visual field arrays）, then shading diaphragm be also required to corresponding array into
