Background technology
An important performance of optical glass is exactly the good spatially uniform of material refractive index.The inside striped of optical glass belongs to the change of space local uniform property.The inside striped of optical glass is some at the glass transparent body of the neither band shape that is same as substrate glass of the composition of component and optical property thereof, wire, netted and veiny.The inside striped of optical glass is very big to influences such as optical instrument intensity, image quality.Along with the development of related industry, more and more stricter to the quality requirements of optical glass.
At present, adopt projecting method usually, judge with human eye to the detection of the inside striped of optical glass.This method is a kind of qualitative detection, and the different detection personnel can obtain the different detection result.The glass that uses tank furnace to produce, inner striped complex-shaped, the shape of these stripeds is similar to the glass metal convection current pattern that freezes, and has increased the difficulty of testing staff's discriminatory analysis.
In addition; Along with the development need of optical instrument compact and lighting, a lot of optical glass product, especially filters; Its size and thickness all reduce thereupon; Existing schlieren instrument is for small size, sample that thickness is little, and is especially relatively poor to the bar detection effect of sheet sample, observes difficult judgment.How accurately the inside striped of test and analysis optical glass has crucial meaning to the production of optical glass.
The utility model content
But the utility model technical matters to be solved provides the bar detection device of the high detection by quantitative of a kind of resolution, can accurately test and analyze the inside striped of optical glass.
The technical scheme that the utility model technical solution problem is adopted is: optical glass bar detection device comprises by light path successively: light-source system, first condenser, first catoptron, second condenser, first diaphragm, branch opto-collection system, collimating mirror, objective table and second catoptron.
Further, said light-source system comprises homogeneous illuminator, optical collector and second diaphragm successively by light path.
Further, said optical collector adopts the square body of glass material.
Further, said homogeneous illuminator is made up of light source and ellipsoidal mirror.
Further, said light source adopts high-pressure sodium lamp or spectrum lamp.
Further, opto-collection system comprised optical splitter, image acquisition device and computing machine successively by light path in said minute, and said image acquisition device links to each other with computing machine.
Further, plated film on said optical splitter.
The beneficial effect of the utility model is: pick-up unit adopts reflective light path detection light to pass through sample twice, has realized optical glass, especially the high-resolution differentiation of small size, the inner striped of sheet sample and the test specification of digitizing quantitative Treatment; Adopt folding vertical observation structure, make things convenient for quick fetching and adjustment sample position.The pick-up unit of the utility model has been realized the extraction of correlated characteristic data; Reduce artificial experience influence, help comparing analyzing and processing, carry out quality monitoring; The accuracy and the stability of the inner striped test of optical glass have been improved, for optical glass production adjustment provides support.

Embodiment
As shown in Figure 1, the pick-up unit of the utility model comprises by light path successively: light-source system 1, first condenser 3, first catoptron 4, second condenser 5, first diaphragm 6, divide opto-collection system, collimating mirror 10, objective table 11 and second catoptron 12.Opto-collection system comprised optical splitter 9, image acquisition device 8 and computing machine 7 successively by light path in said minute, and said image acquisition device 8 links to each other with computing machine 7.
In order to improve the utilization ratio of light source, strengthen the light intensity of striped picture, improve the resolution of striped picture, light-source system 1 can adopt structure shown in Figure 2.Light-source system 1 comprises homogeneous illuminator, optical collector 15 and second diaphragm 16 successively by light path, and wherein, the homogeneous illuminator is made up of light source 2 and ellipsoidal mirror 14.The light that light source 2 sends converges at 16 pairs of emergent lights of optical collector 15, the second diaphragms and selects after ellipsoidal mirror 14 reflection, eliminates stray light.The utility model adopts ellipsoidal mirror 14 to converge, and most light that can make light source 2 send get into pick-up unit, participate in test, have improved the utilization ratio of light source 2 effectively, have strengthened the light intensity of striped picture, help improving the resolution of striped picture.Above-mentioned optical collector 15 adopts the square body of glass material, can improve the homogeneity of light source outgoing beam illumination, helps improving contrast.Light source 2 can adopt high-pressure sodium lamp or spectrum lamp, to realize that the tested glass of different transmitances is carried out bar detection.
The light that the light-source system 1 of the utility model sends is realized the light path turnover through first catoptron, 4 reflection backs behind first condenser 3, select through converging at 6 pairs of emergent lights of first diaphragm, 6, the first diaphragms behind second condenser 5 again, eliminates stray light.The turnover light path that the utility model adopts condenser and catoptron to constitute; Can effectively reduce instrument size; Light-source system 1 is distributed in level and vertical direction respectively with the optical system for testing system; The optical device of conveniently arranging makes the installation adjustment of light-source system 1 and optical system for testing system not disturb mutually, helps installing and observing and regulate.And because light-source system 1 is distributed in different directions respectively with the optical system for testing system, light-source system 1 space enlargement of living in can be installed bigger air cooling system, effectively improves the serviceable life of light source.
Light beam through first diaphragm 6 after, get into to divide an opto-collection system.Divide the optical splitter 9 of opto-collection system to be transmission, reflection device; On optical splitter 9, can plate the different film of transmitance according to actual conditions, after the transmitted light behind the process optical splitter 9 passes through collimating mirror 10 again, parallel inciding on the catoptron 12; The locus of catoptron 12 can be adjusted; To realize the fine setting of sample striped picture, help reducing and eliminate because the different imagings that cause with face type processing situation of sample refractive index are inconsistent, realize detection to different trade mark optical glass inside striped.
On the reflection direction of optical splitter 9, lay image acquisition device 8 and carry out the collection and the observation of image, can effectively reduce hardware requirement like this, improve the stability and the adaptability of detection system image acquisition device 8.After image acquisition device 8 obtains the striped picture, transfer to computing machine 7, computing machine 7 is realized real-time collection and analysis to optical glass inside striped through software.
During test, open light source 2, be placed on inner streaky sample 13 on the objective table 11; As shown in Figure 3, incide sample 13 through the light behind the collimating mirror 10, the light through sample 13 will be reflected or scattering by striped slightly; After catoptron 12 reflections, through sample 13 and after optical splitter 9 reflections, image acquisition device 8 collects the striped picture to light beam once more again; The position of striped in sample 13 will become visible as a dark slightly zone, can see to be the dark-coloured striped image of ash.
