LRS-2/3 Teaching Laser Raman Spectrometer
Monochromator and Spectrometer
Product details
-Instrument Introduction
The LRS-2/3 laser Raman spectrometer is a new product designed by our company. It won the second bid for World Bank loan development projects in 1998 and 2000 due to its simple structure, easy adjustment and measurement, high sensitivity, good stability, and low price. Suitable as a measuring instrument for Raman spectroscopy and fluorescence spectroscopy in research institutes, physics laboratories, and chemistry laboratories of higher education institutions.
