Front side board and back side panel center be provided with a groove, it is convenient to switch on power, the magnetic field of sample surfaces is measured after top cover
Intensity.
Raman spectrometer switches to low power objective（10x）, incandescent light source is opened, the slow object lens that decline are to apart from sample stage
At about 2 millimeters of top cover, fine setting focal length is until the image of sample occurs, and closing incandescent lamp uses telephoto lens instead（50x）And open sharp
Radiant carries out exact focus.Focusing work is finished, and can carry out Raman spectrum test.Focus herein work, be according to sample
In platform sample put height, thickness, and lens focus determine.In the present invention, the upper surface of block 6 is placed apart from top cover upper table
9 millimeters of face（Such as Fig. 3）, the C film thickness for test is less than 1 millimeter, low power objective（10x）And telephoto lens（50x）Jiao
Away from being 10.6 millimeters, therefore, focusing when, can first by object lens drop to naked eyes can distinguish apart from sample stage top cover 2
At millimeter, then it is finely adjusted.
It is to be tested to finish, stop after the operation software of Raman spectrometer, lifting object lens, sample stage can be removed, cut off sample
Sample platform power supply.Sample stage is removed from objective table, top cover is opened, sample is taken out, a whole set of test job is completed.
The embodiment that raman spectroscopy measurement is carried out using sample stage provided by the present invention is taken to the sample stage below
The effect obtained is illustrated.
Embodiment 1：
Test sample：Nano-carbon film 1（Graphene nano-crystal structure）, thickness of sample：200 nm；Excitation wavelength：514 nm are excited
