Description
Technical field
The utility model belongs to spectral measurement field, more particularly, to a kind of grating spectrograph.
Background technology
Grating spectrograph is the most frequently used instrument in spectral measurement, is a kind of sensitivity high, wide adaptability, analyze speed
Hurry up, spectrometric instrument easy to use, can be used for each university and research department, as physics experiment teaching and spectrum analysis work
One of tool.Sometimes lucifuge is needed to operate during fluorescence spectrum is measured, when sample or regulation light path is changed
Always manually to go to control the light switch button on wall；Meanwhile, sample number into spectrum has also been recorded during changing sample, and
And in order that light intensity is most strong, the position of optical path device between sample and grating spectrograph can be also adjusted, now it is also required to record
Light path traveling mode, this results in the increase increased with person works' intensity of experimental period.
Utility model content
In view of this, the utility model is directed to a kind of grating spectrograph, with improve experiment in because dispersion manpower go control
Headlamp switch processed and recording beam path traveling mode and the low problem of the operating efficiency that causes.
To reach above-mentioned purpose, what the technical solution of the utility model was realized in：
A kind of grating spectrograph, including light path cabinet, entrance slit, LED, LED controlling switches and camera, it is described enter
The one end of slit in light path cabinet side is penetrated, the LED on the side where entrance slit, open by the LED controls
Pass is connected on light path cabinet surface and by holding wire with LED, and the camera is fixed on light path cabinet inside.
Further, the LED is positioned close to the position of entrance slit.
Further, the camera gun on the camera is located at light path cabinet surface at entrance slit, takes a picture
Machine controlling switch exposes light path cabinet surface.
Further, the light path cabinet surface is provided with USB interface, and the USB interface is connected to photograph by data wire
On camera.
Relative to prior art, a kind of grating spectrograph described in the invention has the advantage that：
(1) LED of the present invention can for staff carried out under dark surrounds sample exchange provides convenient it is fast
Prompt operation, substantially increases operating efficiency.
(2) camera gun of the present invention makes certain tribute when the regulation of optical path device and record sample are exchanged
Offer, the information transmission that will be shot by USB is stored in computer, reduces the working strength of experimenter.

Specific embodiment
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the invention can
To be mutually combined.
Describe the utility model in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
As depicted in figs. 1 and 2, a kind of grating spectrograph, including light path cabinet 1, entrance slit 2, the control of LED 3, LED
Switch 5 and camera 4, the entrance slit 2 are arranged on the institute of entrance slit 2 in one end of the side of light path cabinet 1, the LED 3
Side on, the LED controlling switches 5 are connected on the surface of light path cabinet 1 and by holding wire with LED 3, the photograph
Camera 4 is fixed on inside light path cabinet 1.
The LED 3 is positioned close to the position of entrance slit 2, so that the light path to the front of entrance slit 2 builds mode
Operated.
On the surface of light path cabinet 1 mounting hole, the photograph on the camera 4 are opened up at entrance slit 2
Machine camera lens is located at the mounting hole, and camera controlling switch 6 exposes the surface of light path cabinet 1, facilitates Taking Pictures recording entrance slit 2
The light path in front builds mode.
The surface of light path cabinet 1 is provided with USB interface 7, and the USB interface 7 is connected to camera 4 by data wire
On, the camera can be transferred data on computer by USB interface.
The course of work of the present embodiment is as follows：
Having some spectral measurements to test is needed to be carried out under dark condition, such as the fluorescence of sample is measured under dark surrounds
In spectrum experiment, opening LED 3 carries out device adjustment work, and sample is fixed on into the front of entrance slit 2, and laser is in grating
The side of spectrometer is irradiated on sample, can be logical using one or more lens and optical filter between entrance slit 2 and sample
Over-focusing optical signal and filtering interference optical signal, the launching light of sample is incided in light path cabinet 1, now presses camera control
The camera of system switch 6 shoots sample and builds mode to the light path between spectrometer and record sample number into spectrum；Close LED 3
And covered operating system with gobo, laser and grating spectrograph are opened, the illumination that laser sends is mapped on sample to be made
Sample produces launching light, and light is entered into light path cabinet 1 by entrance slit 2, and, this time is by letter from exit slit out
Number reception device carries out signal and amplifies and be delivered in computer software, so far just completes an experiment for sample；
Then the lightening LED lamp 3 of LED controlling switches 5 opened on light path cabinet 1 is illuminated, and changes sample and adjusts light
Mode is built on road, then presses camera controlling switch 6 Taking Pictures recording is carried out to it, and sample is tested before subsequent operation is repeated
The step of.
Preferred embodiment of the present utility model is the foregoing is only, is not used to limit the utility model, it is all at this
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc. should be included in the utility model
Protection domain within.
