The main body of it is a flat optics glass plant and the surface to one of it is frosted surface with grain tape. The grain radius is corresponding to the bigger radius of aerosol in gas. Its physical and chemical stability is strong by using optics glass. It achieves well production consistency for very mature frosted and plating film technology. It achieves series of adjust plant to finish the more point testing and adjust to get better adjust visibility appearance production.
Description
Technical field
The present invention relates to a kind of optical alignment equipment---the forward scattering visibility meter calibrating plate in the visiometer belongs to the atmospheric optics field.
Background technology
Forward scattering visibility meter calibrating plate (to call calibration plate in the following text) manufacturing technology belongs to the atmospheric optics field, and it is a kind of optical alignment equipment, and it is mainly used in the adjustment of forward scattering visiometer (to call visiometer in the following text).Calibration plate is as the necessary auxiliary product of visiometer, and it mainly is an aerocolloidal scattering properties in the certain atmosphere of simulation, and quantitative is corresponding with scattering coefficient, with this demarcation and detection reference as the visiometer product.Key in the visiometer production is that last instrument is always transferred, it is directly connected to measurement range and measuring accuracy, and the key in total the accent is to adopt the calibration plate of the certain scattering coefficient of a series of correspondences to come calibrating instrument, also will be equipped with the respective alignment plate after the good instrument of demarcation dispatches from the factory uses as instrument detecting adjustment in the future, so the invention of calibration plate is most important with creation.
Summary of the invention
At the problems referred to above, the object of the present invention is to provide a kind of forward scattering visibility meter calibrating plate, to simulate aerocolloidal scattering properties in certain atmosphere, quantitative is corresponding with scattering coefficient, with this demarcation and detection reference as the visiometer product.
For achieving the above object, technical scheme of the present invention is: a kind of forward scattering visibility meter calibrating plate, the main body of this calibration plate is the planar optics glass plate, one of them plate face of optical flat is that the surface presents granular matte surface, and the radius that gasoloid is bigger in its particle radius and the atmosphere is corresponding.
Another plate face of described optical flat is that the surface presents granular matte surface equally, and the radius that gasoloid is bigger in its particle radius and the atmosphere is corresponding.
Another plate face of described optical flat is the surperficial plated film face that carries out plated film, and rete is a chromium.
The design of this calibration plate has the following advantages and effect: because material selection optical glass, its physics, chemical stability are strong, utilize this frosted and coating process can make product reach good consistance.Adopt the technical program calibration plate can be made seriation, reach the purpose that multiple spot detects calibration, be beneficial to better adjustment visiometer product, this does not at home and abroad have.

Embodiment
Calibration plate is a kind of equipment of simulating the atmospheric scattering characteristic, and in atmosphere, the decay of light is caused by scattering and absorption.Yet in the ordinary course of things, absorption factor can be ignored, and via the water droplet reflection, the scattering phenomenon that refraction or diffraction produce constitutes the main factor that reduces visibility.So atmospheric extinction coefficient can be thought and scattering coefficient equates.Therefore, the manufacturing materials of calibration plate should be low absorbing material, simultaneously, requires it to have light scattering.In the selection of material, we tend to thermally-stabilised, wear-resisting, corrosion resistant optical glass, for example K9 glass; On method for making, utilize the processing technology of frosted and plated film to handle, accomplish process and controllability as a result.Concrete scheme is as follows:
In order to simulate atmospheric scattering, we utilize the job operation of surperficial frosted, make glass surface present graininess, and the radius that gasoloid is bigger in its particle radius and the atmosphere is suitable, promptly imitate the thick fog state of atmosphere; At this moment, the sand grains of choosing which kind of sand number finish grindes processing and has become key with the effect that obtains, and through test in a large number, we have finally chosen W7 sand.Through this processing, can reach the purpose of imitation atmospheric scattering.When imitating very low visibility (as 5 meters), can two-sided frosted; And when needing bigger visibility, can the single face frosted, another side is handled in order to method down.
In order to make the bigger visibility value of calibration plate simulation, as 20 meters, we must be on the basis of above frosted, achieve the goal by controlling its scattered quantum, at this, we utilize the job operation of one side frosted another side plated film to realize that rete is a chromium, by the transmitance of control plated film, can obtain the calibration plate of multiple visibility nominal.The transmitance that has commonly used is 5%-6%, corresponding 20 meters left and right sides visibility values, and transmitance is 1%-2%, corresponding 150 meters left and right sides visibility values.
As Fig. 1, shown in Figure 4, one of them plate face of optical flat 1 is that the surface presents granular frosting 2, and the radius that gasoloid is bigger in its particle radius and the atmosphere is corresponding.
As Fig. 2, shown in Figure 4, one of them plate face of optical flat 1 is that the surface presents granular frosting 2, and the radius that gasoloid is bigger in its particle radius and the atmosphere is corresponding.Another plate face of optical flat is the surperficial plated film face 3 that carries out plated film, and rete is a chromium.
Embodiment 3
As shown in Figure 3, Figure 4, wherein two plate faces of optical flat 1 are the surface and present granular frosting 2, and the radius that gasoloid is bigger in its particle radius and the atmosphere is corresponding.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within the claim scope of the present invention.
