Raman spectrometer / CCD / high-sensitivity
StellarNet offers a variety of high performance spectrometers configured for 532nm Raman spectroscopy applications that perform quick identification of a variety of liquid, solid, or powder samples. 532nm laser excitation is a common wavelength chosen for Raman spectroscopy. This is because the Raman scattering efficiency in this region is very high. Green lasers typically can be good for metal oxides, minerals, or other inorganic materials and resonance Raman experiments (e.g. for carbon nanotubes and other carbon materials). Since scattering efficiency is high, there is less need for high power excitation which could possibly burn darker samples. Also, spectrometers configured for 532nm Raman can cover a wider wavenumber shift such as 200-5,250 cm-1 which allows you to see valuable information such as -NH and -OH functional groups found at 2,800 and 3,700cm-1 respectively.
Raman-HR-TEC-532 Spectrometers are our most popular 532 Raman spectrometers and include an enhanced CCD array detector tuned for 532nm Raman with advanced detector lens assembly for ultra sensitivity at long exposure times.
Raman-ER-TEC-532 Spectrometers extended range Raman spectrometers include an enhanced CCD array detector tuned for 532nm Raman with advanced detector lens assembly for ultra sensitivity at long exposure times.
Raman-HR-TEC-X2-532 Spectrometers offers 2-stage detector cooling for ultimate sensitivity and performance! Great for long exposures up to 8 minutes.
