China Wholesale Fourier Spectrometer Pricelist – LGS-1 Laser Raman Spectrometer – Labor

Short Description:

By measuring the power, voltage and current of a semiconductor laser, the students can understand the working characteristics of a semiconductor laser under continuous output. Optical multichannel analyzer is used to observe the fluorescence emission of semiconductor laser when the injection current is less than the threshold value and the spectral line change of laser oscillation when the current is larger than the threshold current.

China Wholesale Fourier Spectrometer Pricelist – LGS-1 Laser Raman Spectrometer – Labor Detail:

LGS-1 Laser Raman Spectrometer is a useful instrument for the identification of a wide range of substances in physics and chemistry laboratories of scientific research institutes and universities.

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
