Embodiment
Below in conjunction with accompanying drawing, the preferred embodiment of the invention is described in detail:
Laser on-line checkingi power meter as depicted in figs. 1 and 2, mainly comprises holder 1, light splitting piece 2, mirror holder 3, frosted glass 4, optical filter box 5 and photodetector 7 etc.
Wherein, holder 1, in " convex " shape, is provided with through hole in the middle part of it, and its top is provided with the fixed head with its one.Mirror holder 3 is arranged on holder 1 by fixed head, its bottom is provided with and forms acute angle light splitting piece 2 (in the present embodiment with surface level, the angle that light splitting piece 2 and surface level are formed is preferably 45 °), its top is provided with the frosted glass 4 corresponding with light splitting piece 2.Optical filter box 5 is arranged on mirror holder 3 side, and it is corresponding with frosted glass 4; Diaphragm 6 is fixed on the end of optical filter box 5; Photodetector 7 is connected with optical filter box 5, and passes the middle part of diaphragm 6.Utilize light splitting piece 2 pairs of laser to carry out light splitting, decayed by frosted glass 4 scattering, optical filter box 5, irradiation by AD conversion, obtains real time laser power to the laser energy on photodetector 7; Its repeatability is good, is easy to assembling, and structure is simple, is adapted to the on-line checkingi of the laser of higher-wattage.
In the present embodiment, light splitting piece 2 is not coated glass sheet, and its thickness is 5 ~ 10 millimeters, specifically can use Wuhan You Guang company without plated film 6mm diaphragm.Frosted glass 4 granularity is preferably 100 ~ 150, and specifically can use the 10mm Diameter 120Grit Ground Glass Diffuser#83-082 of Edmund company of the U.S., #83-082 has good low scattering loss, can get stable diffused light source.Frosted glass 4 is in the light with baffle plate, reduces interference of stray light.Diaphragm 6 selects general camera iris.The excellent smooth 10mm attenuating filters in Wuhan selected by optical filter box 5, OD=10.
The above-mentioned structure to the utility model laser on-line checkingi power meter is illustrated, and does to explain in detail below to its principle of work:
First installing laser on-line checkingi power meter makes laser to be detected be radiated on light splitting piece 2, light splitting piece 2 adopt 6mm thick without plated film k9 glass, thus 2% of reflects laser different wave length luminous energy (remaining 98% through light splitting piece 2); The laser of reflection exposes on frosted glass 3, through its diffuse reflection, expose to optical filter box 5 to decay, recycling diaphragm 6 filters parasitic light, thus reach the object of the power obtaining stabilized light source, final effective light input photodetector 7, through AD standard change obtain photoelectricity standard change after voltage.
Above-described embodiment is only for illustrating technical conceive of the present utility model and feature; its object is to person skilled in the art can be understood content of the present utility model and implement according to this; protection domain of the present utility model can not be limited with this; all equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
