Introduction    

This spectrometer is designed to help students understand the concepts of light and wave phenomena and learn how a grating spectrometer works. The modular structure provides flexible solutions for spectral measurements. Emission and absorption spectra can be measured. It is also a valuable analytical tool for the studies and characterizations of optical filters and light sources.
