Abstract
A multifunctional grating instrument comprises a diffraction grating, a double-sided plane mirror and a base, wherein the diffraction grating has a cuboid shape and has a height of 40mm and a width of 35mm; the double-sided plane mirror has a cuboid shape and has the height of 40mm and the width of 25mm; the diffraction grating is identical to the double-sided plane mirror in thickness; the base has a concave shape, and has the height of 12mm, and the length of 60mm, wherein the width of low bottom surface of the base is 14mm; a groove with the depth of 5mm is formed in the base along the length direction; the width of the groove is larger than the thickness of the diffraction grating; and the base is made of stainless steel. When the grating instrument is in use, the diffraction grating and the double-sided plane mirror are sequentially clamped into the groove close to each other; the base is placed on an object stage of a coarsely tuned spectrometer; and the diffraction grating and the double-sided plane mirror respectively face auto-collimation telescope lens barrels on the spectrometer. Therefore, the multifunctional grating instrument respectively performs the functions of the diffraction grating and the double-sided plane mirror, and has the beneficial effects of simplicity, convenience, practicability, safety, and obvious test effect.
Description
Technical field
The utility model belongs to the physical experiment apparatus field, relates 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 utility model is to provide a kind of multi-functional grating instrument, and the function of existing grating has again the function of level crossing.
the technical scheme that its technical matters that solves the utility model adopts 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 greater 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 beneficial effects of the utility model are, simple and convenient practicality, experiment effect obviously, safety.
