Abstract
The utility model provides a stripe detection device which can clearly observe the stripe image, which comprises a light source, an optical-collecting imaging part, an aperture plate, a collimation imaging part, a sample platform, a projecting screen and a vidicon, which are sequentially arranged along a light path. The stripe detection device is provided with the imaging part, and the stripe is observed in a parallel light path, so the observation of the stripe is clearer compared with the divergence light path; all parts are installed on a base, and the base can slide on an optical guide rail, so the position of each part is adjustable so as to obtain the best imaging effect; the aperture holes with different sizes can be selected to obtain the appropriate light intensity and to eliminate the stray light.
Description
Technical field
The utility model relates to a kind of bar detection device of optical glass.
Background technology
The striped of optical glass is that industrial chemicals produces when being fused into glass, and striped is very big to the imaging optical instrument imaging quality influence, and serious striped can increase the fragility of glass, reduces the shock resistance of glass, anti-opening and mechanical property such as resistance to compression.Along with the development of photoelectric digital product, more and more tighter to the quality requirements of optical glass, how the striped degree of measuring optical glass is just more and more important.
Present bar detection device all adopts sciagraphy to measure, as shown in Figure 1, this device comprises successively along light path: light source 1, pin hole light hurdle 2, be placed on specimen holder 3, projection screen 4 and ccd video camera 5 on the universal stage, only dispersing of light source 1 emission, when not placing sample, the light chart on the projection screen 4 is the hot spot of a homogeneous and bright; After putting into streaky sample on the specimen holder 3, just can see on the projection screen 4 to be the dark-coloured striped image of ash, then according to GB/T7962.7-1987 " colouless optical glass method of testing striped degree method of testing " classification deciding grade and level.But the striped image that adopts this device to observe is not very clear.
The utility model content
Technical problem to be solved in the utility model provides a kind of bar detection device that can clearly observe the striped image.
The technical scheme that the utility model technical solution problem is adopted is: the bar detection device comprises successively along light path: light source, optically focused image-forming block, aperture plate, collimation image-forming block, sample stage, projection screen and video camera.
The beneficial effects of the utility model are: the utility model is provided with image-forming block, observes striped in parallel light path, and light path observation is more clear with respect to dispersing; All parts are installed on the base, and base can slide on the optics guide rail, make that each position component is adjustable, to obtain best imaging effect; The aperture that can choose different sizes obtains suitable light intensity, and eliminates parasitic light.
