Dual-Band Raman Spectrometer
application
The ATR3220 dual-band Raman spectrometer has two wavelengths of laser light source concentrated inside. The two excitation wavelengths are coaxially excited. There is no need to move the probe when switching the optical path, so the same position of the test sample can be achieved with different excitation wavelengths.
ATR3220 uses a spectrometer with a focal length of 150mm, a resolution of up to 3cm-1, and a built-in dual rotating grating, which can perform both wide-band Raman testing and high-spectral resolution Raman measurement.
ATR3220 has built-in ultra-narrow linewidth lasers with excitation wavelengths of 532nm, 638nm, and 785nm (2 optional), with a maximum power of 550mW; and a variety of cooling detectors are available, with a cooling temperature of -70°C; at the same time, combined with high-reliability optical design, circuit design, and structural design, the measurement results are very stable and the signal-to-noise ratio is extremely high.
ATR3220 features high flexibility and high resolution. It can perform both wide-band Raman testing and high-spectral resolution Raman spectroscopy testing. It has the advantages of high cost performance and small sample size. It can be expanded to liquid testing and is very suitable for identification of textiles, biology, alcohol, crystals, biomedicine, research institutes, pharmaceu industry, chemical reactions, scientific research and biological processes.
