use:
The 31W one-meter plane grating spectrograph is a classic product produced by our company. This instrument uses plane reflection grating spectroscopy to study the composition and content of substances. It is mainly used for daily qualitative and quantitative analysis of metal alloys (including mineral mine stones), and identification of impurities in pure metals and materials. Zone analysis, recording flash and low light phenomena.
Instrument features:
1. The optical system adopts the Albert vertical symmetry device, the coma and astigmatism can be corrected to the ideal level, the spectral line is clear in the long spectral range, the structure is uniform, and the sensitivity is high.
2. The instrument adopts a three-lens achromatic illumination method, and the slit is uniformly illuminated, so that the blackness of the same spectral line is uniform.
3. Hartmann diaphragm and third-order, nine-valent light-reducing plate before the instrument slit.
4. Use a control box to control the spectrum process.
5. The instrument is equipped with DC arc and AC arc light sources to meet the needs of different analysis tasks.
6. The instrument is equipped with a workbench, which is easy to install and operate.
7. The spectral lines are fresh at the standard wavelength of the iron sample in the pretreatment stage.
8. Center wavelength display realizes UI interface and human-computer interaction.
9. Adopt high-precision screw and grating to adjust the center wavelength.
10. The instrument adopts full digital control, which can realize the automation of phase plate movement.
11. The instrument realizes full digital display, and can directly display the time and center wavelength of pre-burning, exposure, plate movement.
