Description
Technical field
The utility model provides the adjustable laser attenuator of optical field.
Background technology
When carrying out laser power test, the light path generally required between laser beam and laser power meter adds laser
Attenuator, reduces laser power, it is to avoid power meter is caused to damage, due to needing to change declining for differential declines coefficient in test
Subtract device, so frequent operation, adds the testing time, waste the time and efforts of experimenter, and laser can not be carried out fast
Speed test.
The content of the invention
In order to overcome the technical problem that laser testing efficiency is low, the continuous decay to laser different multiples, this practicality are realized
It is new to provide adjustable laser attenuator.The attenuator on the first runner and the second runner by being respectively mounted laser attenuation
Piece, by the rotation of runner, overlaps different light transmittance attenuators, so as to carry out artificial adjustable laser attenuation test, solves to swash
The technical problem of optical tests efficiency.
The utility model solves the scheme that is used of technical problem：
It is separated by base by rotating shaft and the first runner and the second runner is installed, 6 is provided with each runner and is declined
Subtract piece mounting hole, attenuator, including the first attenuator and the second attenuator are fixed with each mounting hole.
Equipped with 6 decay film perforations on each runner, wherein 1 is not installed attenuator, it is through hole, 5 attenuators are in addition
Attenuator with different light transmittances, the attenuator has gradient light transmittance.
Good effect, because the utility model has laid laser attenuation piece on former and later two runners, by rotating shaft,
Adjust attenuation coefficient.With regulation often, easily regulation, the wide advantage of adjustable extent.Suitably as the device of laser attenuation
Use.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the utility model side view.
In figure, 1. first runners, the attenuators of 1.1. first, 2. second runners, the attenuators of 2.1. second, 3. rotating shafts, 4. bottoms
Seat.
Embodiment
According to the figure, it is separated by base 4 by rotating shaft 3 and first runner 1 and the second runner 2 is installed, in each runner
On be provided with 6 attenuator mounting holes, be fixed with attenuator in each mounting hole, including the first attenuator 1.1 and the second decay
Piece 2.1.
First runner installs 5 laser attenuation pieces, leaves 1 through hole, and the second runner installs 4 laser attenuation pieces, leaves 2
Individual through hole.
The attenuator has gradient light transmittance.
Technical principle：
Laser is light beam, after light beam is propagated in atmosphere runs into photoresistance, will be decayed, and different photoresistance pad values are different,
In order to artificially manufacture photoresistance, using the attenuator of different light transmittances, it is equal to change when the attenuator of different light transmittances is overlapped
Attenuation rate, such as when 1 attenuation rate is 1, when 2 attenuators are overlapped, is equal to the coincidence numerical value of 2 attenuators, then increases
One times is added.Different multiplying attenuator is artificially manufactured by the device, by the rotation of runner, the photoresistance of different multiplying is adjusted,
With the pad value of the different light transmittances of this testing laser.
It is of the present utility model to use：
Lasing source is placed in the front side of the first runner, the first runner is rotated, laser is declined by the first runner laser
Subtract piece and be transmitted to the second runner, rotate the second runner, make the laser attenuation piece of the second runner and the laser attenuation piece of the first runner
Coincide, attenuation multiple now for the first runner attenuation multiple and the second runner attenuation multiple and, by rotating the first runner
With the second runner, the laser attenuation piece of the first runner is overlapped respectively with the laser attenuation piece of the second runner, can be achieved 36 kinds not
With combination, with 36 attenuation multiples, the laser power testing requirement of different capacity range is met, laser power measurement is expanded
Scope.
First runner installs 5 laser attenuation pieces, leaves 1 through hole, and the second runner installs 4 laser attenuation pieces, leaves 2
Individual through hole.Can so there are 30 kinds of selections, be easy to experiment to adjust.
