LGS-3 Modular Multifunctional Grating Spectrometer/Monochromator
LGS-3 Modular Multifunctional Grating Spectrometer
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 under photomultiplier (PMT). It is also a valuable analytical tool for the studies and characterizations of optical filters and light sources.
Functions
1. Understand and master the working principle and application of spectrometers
2. Absorption spectroscopy measurement: can analyze the absorption spectrum of the measured substance (gas, liquid, solid)
3. Emission spectrum measurement: measuring the spectral characteristics of the emitting light source
4. Measurement of Rydberg constant using hydrogen spectroscopy, measurement of sensitivity characteristics of receiving elements, and measurement of chromaticity
