Embodiment
The embodiment of the deflectoscope provided below in conjunction with the accompanying drawings the present invention elaborates.
Prism be it is a kind of made by transparent material, and section optical instrument triangular in shape.During accompanying drawing 1 is prism
The route map that light is propagated.As shown in figure 1, the light 1,2,3 of left surface different incidence angles enters after prism from air, 2-1
It is the fringence in prism with 3-1, refraction angle is less than incidence angle, and 1-1 presses former route and advanced；2-2 and 3-2 is in air
Fringence, refraction angle is more than incidence angle, and 1-2 is the ray that is all-trans in prism.Because：
(1) emergent ray will to bottom surface (the 3rd side) deviation, the size of deflection angle and the refractive index of prism, prism
Drift angle is relevant with incidence angle；
(2) when in light is slanted through other media from air, refraction angle is less than incidence angle, and refracted light is to close to normal
Direction deviation；
(3) when light is slanted through air from other media, refraction angle is more than incidence angle, and refracted light is to away from normal
Direction deviation, i.e. base deviation from refracted light to prism.
Based on above-mentioned principle, present embodiment provides a kind of deflectoscope, and accompanying drawing 2 is specific implementation of the present invention
The left view of the deflectoscope of mode, accompanying drawing 3 is the right view of the deflectoscope of the specific embodiment of the invention.
As shown in Figure 2,3, the deflectoscope described in present embodiment includes First Five-Year Plan terrace with edge 11；Wherein, described five
Terrace with edge 11 includes seven smooth flats, i.e., described five terrace with edge 11 is interconnected to constitute by seven smooth planes.Seven light
Sliding plane includes：One binding face 111, including the first graduated scale 1111 and the second graduated scale 1112, and first graduated scale
1111 and second graduated scale 1112 be mutually perpendicular to, the binding face 111 be used for fitted with the transparent body to be measured；One sightingpiston
112, it is connected with the binding face 111, and be in a predetermined angle with the binding face 111.Wherein, described predetermined angle this area
Technical staff can be set as needed, preferably 0-90 degree.By using said structure, a transparent body to be measured with it is described
After binding face 111 is fitted, the defect of the transparent body and nontransparent binding site will be projected to the observation after reflected, refraction
Face 112, user just can be clearly seen that the form of defect in the sightingpiston, and by the graduated scale on the binding face,
The length of the defect, width, height can also be quantified so that user more understands the volume size of defect, is easy to
Take corresponding counter-measure.
In order to not influence being brought into close contact for the binding face and the transparent body to be measured, it is preferred that as shown in Fig. 2 described
First graduated scale 1111 and second graduated scale 1112 are respectively arranged at the two edges of the binding face 111.
It is excellent in order in the case where ambient light is dark, also can clearly check the defect of the transparent body embedded part
Choosing, in seven smooth flats also include a lighting device mounting surface 113, the lighting device mounting surface 113 with it is described
Binding face 111, the sightingpiston 112 are connected, for installing lighting device 12.For example, being set on the lighting device mounting surface 113
A disc cassette fixer is equipped with, to fix a lighting device 12 so that the light that the lighting device 12 is sent is injected described
Inside five terrace with edges 11, so as to illuminate the transparent body embedded part and the sightingpiston 112.
In order to reduce the volume of the deflectoscope, while reducing the cost of the deflectoscope, it is preferred that described
Lighting device 12 is a flashlight.
In order to prevent influence of the ambient light to deflectoscope inspection result, it is preferred that in seven smooth flats
Also including five sides, i.e. first side 113, the side 116 of the side of second side the 114, the 3rd the 115, the 4th and bottom surface (in figure not
Draw), five sides are by pitch-dark covering.Wherein, when the first side 113 is lighting device mounting surface, in order to
Ensure that the luminous energy of lighting device is smoothly injected inside five terrace with edge, the lighting device installation portion in the first side is uncoated
It is pitch-dark.
In order to clearly observe the defect of the transparent body embedded part, it is preferred that five terrace with edge uses gelatin
Glass is made.
In order to make to completely cut off air between the binding face 111 and the transparent body to be measured in detection, enable light wave fully
Incide inside the transparent body to be measured, apply and spread by couplant between the binding face and the transparent body to be checked, it is ensured that be described
Binding face is coupled as the continuous media of light propagation with the transparent body to be measured, so as to check the transparent body by the sightingpiston 112
The defect situation of embedded part, and pass through the length and height of graduated scale reading defect.Wherein, the couplant can be coating
In on the transparent body to be measured or being coated on the binding face 111.It is furthermore preferred that the couplant be glycerine, machine oil or
Water.
The deflectoscope that the present invention is provided, by being improved to existing prism, utilizes the refraction of light, reflection
Phenomenon, the defect of transparent body embedded part is projected on sightingpiston so that user can clearly check that the transparent body is embedding
Enter part with the presence or absence of defects such as crackle or degummings, while by setting graduated scale in binding face, can be time saving by quantifying defects
It is laborsaving, efficiently and accurately.
Embodiment 1
Accompanying drawing 4 is the structural representation of the embodiment of the present invention 1.Glass 41 to be checked is embedded in polyester belt 42 by being glued,
In order to check whether there is degumming phenomenon.First, the daubing coupling agent glycerine on glass 41 to be checked, defect of the present invention is examined
The binding face for looking into instrument is fitted with the glass 41 to be checked, and is excluded by glycerine between the glass to be checked 41 and the binding face
Air, make to be coupled as the continuous media of light propagation between binding face and glass to be checked 41.In order to clearly observe, this
Embodiment is also provided with flashlight 44 on the lighting device mounting surface 45 of the deflectoscope, and the light of the flashlight is injected
Inside the deflectoscope.
Through the sightingpiston 43 of deflectoscope of the present invention, look round between glass 41 to be checked and polyester belt 42
Adhesion zone, a piece of if what is turned white, that is air layer, shows degumming；If uniform brown or terylene tape is presented
