Introduction: The WDS-8/8A combined multifunctional grating spectrometer adopts the modular structure of building blocks, and the dual exit slits are respectively received by CCD and photomultiplier for data analysis. It is designed for basic physics hydrogen deuterium experiments and sodium spectroscopy experiments. The resolution of the instrument can reach 0.06nm (Figure 1, 2). The product is mainly used for university physics experiment teaching and various scientific research units for spectral analysis. Experiment content: 1. Understand the working principle and application of grating spectrometer. 2. Master the technique of using grating spectrometer to measure and map the spectra of different substances. 3. Optionally add a sample cell to measure the transmittance and reflectance of samples with low accuracy requirements.
