Abstract
A multifunctional grating instrument comprises a diffraction grating, a double-sided plane reflecting mirror and a base seat, wherein the diffraction grating is of a cuboid shape and is 40 millimeters high and 35 millimeters wide. The double-sided plane reflecting mirror is of a cuboid shape and is 40 millimeters high and 25 millimeters wide. The thickness of the double-sided plane reflecting mirror is equal to the thickness of the diffraction grating. The base seat is of a concave shape and is 12 millimeters high. The width of a bottom surface of the base seat is 14 millimeters, and the base seat is 60 millimeters long. A groove is formed along the length direction. The depth of the groove is 5 millimeters, and the width of the groove is slightly larger than the thickness of the diffraction grating. The base seat is made of stainless steel. When the multifunctional grating instrument is used, the diffraction grating and the double-sided plane reflecting mirror are enabled to be sequentially clamped into the groove in an abut-against mode. The base seat is placed on a spectrometer cargo-carrying platform which is roughly adjusted, and the double-sided plane reflecting mirror and the diffraction grating are enabled to respectively and rightly face auto-collimation telescope barrels on the spectrometer. The multifunctional grating instrument plays roles of the double-sided plane reflecting mirror and the diffraction grating respectively and has the advantages of being simple, convenient and practical to use and obvious and safe in experiment effect.
Description
Technical field
The invention belongs to the physical experiment apparatus field, relate to a kind of multi-functional grating instrument.
Background technology
The mensuration of separation and line wavelength is that of Experiment of College Physics often does experiment, this experimental optical grid face is as reflecting surface, when adopting autocollimation method and half and half adjusting method to regulate spectrometer, due to the grating printing opacity, reflected light dies down, can not find the reflection image of green crosshair in the auto-collimator visual field of being everlasting, experiment can't be continued.
Summary of the invention
In order to solve the problem of existence, the purpose of this invention is to provide a kind of multi-functional grating instrument, the function of existing grating has again the function of level crossing.
the technical solution adopted for the present invention to solve the technical problems is: multi-functional grating instrument, comprise diffraction grating, two-sided planar catoptron and base, it is characterized in that: described diffraction grating is cuboid, be highly 40 millimeters, width is 35 millimeters, described two-sided planar catoptron is cuboid, be highly 40 millimeters, width is 25 millimeters, thickness is the same with diffraction grating, described base is concave shape, be highly 12 millimeters, 14 millimeters of the face widths of going to the bottom, long 60 millimeters, be provided with along its length groove, the degree of depth of groove is 5 millimeters, width is slightly larger than the thickness of diffraction grating, described base is made by stainless steel.
During use, diffraction grating, two-sided planar catoptron are close to successively snap in groove, base is put on the spectrometer article carrying platform that has adjusted, allow the auto-collimator lens barrel of two-sided planar catoptron on the spectrometer, this moment, multi-functional grating instrument can be used as the use of two-sided planar catoptron, because its reflected light is stronger, easily find the reflection image of green crosshair in the auto-collimator visual field; After seeing the reflection image of green crosshair, movable base allows the auto-collimator lens barrel of diffraction grating on the spectrometer, just is easy to find the reflection image of green crosshair in the auto-collimator visual field, at this moment, multi-functional grating instrument uses as diffraction grating.
The invention has the beneficial effects as follows, simple and convenient practicality, experiment effect is obvious, safety.
