China Wholesale Grating Spectrometer Factories – LGS-3 Modular Multifunctional Grating Spectrometer/Monochromator – Labor Detail:

Note: computer not included

Description

This spectrometer is designed to help students understand the concepts of light and wave phenomena and learn how a grating spectrometer works. By replacing the default grating in the spectrometer with a different grating, the spectral range and resolution of the spectrometer can be altered. The modular structure provides flexible solutions for spectral measurements under photomultiplier (PMT) and CCD modes, respectively. 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.

Functions

To calibrate the spectrum of a selected work window in CCD mode, at least two standard spectral lines are needed within the spectral range of the work window.
