Introduction
LGS-1/1A Laser Raman Spectrometer is a useful instrument for the identification of a wide range of substances in physics and chemistry laboratories of research institutes, universities and colleges. It is a straight forward, non-destructive technique requiring no sample preparation, and it involves illuminating a sample with monochromatic light and using a spectrometer to examine the light scattered by a sample.
Features
Slit option for stray light suppression
Monochromatic system with high resolution
Single-photon counter detector with high sensitivity and low noise
High accuracy, stable external optical path
