In order to save regulating time, the quickly regulating method of many spectrometers is suggested, wherein laser auxiliary adjustment
Method experiments verify that, the adjusting part of completion experiment that can be quickly, and laser auxiliary control can make student in adjusting process
In be better understood from the variation of light path.But current laser auxiliary control device is there are the difficult realization of technique, device is complicated, makes
The problems such as of high cost.
Utility model content
The utility model in order to solve the problems in the existing technology, provide it is a kind of adjust it is simple, at low cost and be convenient for
The laser auxiliary control device of carrying.
In order to achieve the above object, the utility model proposes technical solution be：A kind of laser assisted Spectromenter Adjustment dress
It puts, is installed on the lens barrel of spectrometer telescope, including semiconductor laser and a pair of mutually symmetrical with clamping plate, the clamping plate bag
Include the first clamping part and the second clamping part, the first clamping part semicircular in shape, for being clamped in the lens barrel of telescope, second
Clamping part is arc-shaped and positioned at one end of the first clamping part, and the semiconductor laser is located at the second clamping part.
Above-mentioned technical proposal is further designed to：The clamping plate further includes two and picks up the ears, and picks up the ears for two to be located at respectively
The both ends of clamping plate, described to pick up the ears to be equipped with through hole, the through hole is equipped with screw.
The optical axis of the telescope is parallel with the optical axis of semiconductor laser.
The clamping plate is an integral structure.
A diameter of 5mm of the semiconductor laser.
The beneficial effects of the utility model are：
1st, the device of the utility model is adjusted simple, and student can be made to be quickly completed the adjusting of spectrometer experiment, saved tune
Save the time.
2nd, laser is fixed on lens cone for telescope one side by two clamping plates and can be realized to spectrometer by the utility model
Auxiliary adjustment, it is simple in structure, be easily achieved and low manufacture cost.
3rd, due to the lens cone for telescope one side that laser is located in the utility model, the light path of telescope ocular will not be made
Into influence, after the completion of adjusting, which is also not required to disassemble from telescope, easy to use to cause telescope etc.
The damage of instrument.
Description of the drawings
Fig. 1 is the structure diagram of the utility model embodiment.
Specific embodiment
Below in conjunction with the accompanying drawings and the utility model is described in detail in specific embodiment.
Embodiment
As shown in Figure 1, a kind of laser assisted Spectromenter Adjustment device of the present embodiment, including semiconductor laser 1 and one
To mutually symmetrical with clamping plate 2, middle clamp plate 2 includes the first clamping part and the second clamping part, and the first clamping part semicircular in shape is used for
It is clamped on the lens barrel of telescope, the second clamping part is arc-shaped and positioned at one end of the first clamping part, semiconductor laser 1
At the second clamping part, power supply 4 is used to power for semiconductor laser 1, and power supply 4 is connected by conducting wire with semiconductor laser 1.
For the ease of the fixation of clamping plate 2, the present embodiment is additionally provided with two on clamping plate 2 and picks up the ears 21, two 21 difference of picking up the ears
Positioned at the both ends of clamping plate 2, pick up the ears to be equipped with through hole, through hole is equipped with screw 3, and two clamping plates are fixed on by screw 3 and nut 4
Together.
In the present embodiment, clamping plate is an integral structure, and improves the globality of whole device.
The a diameter of 5mm for the semiconductor laser 1 that the present embodiment uses, and the optical axis of telescope and semiconductor laser 1
Optical axis it is parallel.
The step of spectrometer experiment is adjusted using the laser assisted Spectromenter Adjustment device of the present embodiment be：
1st, focus
Prism optical surface in experiment is adjacent to lens cone for telescope, adjusts the focusing screw of eyepiece, makes to see in visual field
To clearly green cross.
2nd, coarse adjustment
Laser power supply is opened, adjusts prism optical surface, the hot spot of laser reflection can be seen on clamping plate, using each
Half adjusting method causes the hot spot of two optical surface reflections of prism to be overlapped with laser light-emitting window, and coarse adjustment at this time is completed.By
Straightforward very well in laser quasi, fine tuning at this time has substantially also been completed, but still needs to carry out fine tuning inspection with telescope.
3rd, fine tuning
The position of the green cross of two optical surface reflections of prism in visual field is observed, if overlapped with upper crosshair,
Then fine tuning has been completed；If misaligned with upper crosshair, fine tuning telescope pitching screw is allowed to coincidence.Telescope at this time
Optical axis it is vertical with prism optical surface and spectrometer central rotating shaft respectively, adjusting is partially completed.
The laser auxiliary adjustment of the present embodiment, because the hot spot of laser reflection can be seen, student is according to reflection
The position of hot spot can be well understood by the inclination size of prism and telescope, can just be completed well using Both-half Adjusting Method
The adjusting of spectrometer.The device has greatly saved the time adjusted, also student can be allowed to be best understood by telescope Green ten
The variation that word is generated with the variation at prism and telescope inclination angle.
The laser assisted Spectromenter Adjustment device of the utility model is not limited to the various embodiments described above, all to use equivalent substitution
The technical solution that mode obtains is all fallen in the range of the requires of the utility model protection.
