633nm Example Raman Spectra-
StellarNet offers a variety of high performance spectrometers configured for 633nm Raman spectroscopy applications that perform quick identification of a variety of liquid, solid, or powder samples. 633nm laser excitation is a common wavelength chosen for Raman spectroscopy as it has a good balance between Raman efficiency, low fluorescence, and affordability.
Raman-HR-TEC-633 Spectrometers include an enhanced CCD array detector tuned for 633nm Raman with advanced detector lens assembly for ultra sensitivity at long exposure times.
Raman-HR-TEC-X2-633 Spectrometers offers 2-stage detector cooling for ultimate sensitivity and performance! Great for long exposures up to 8 minutes.
Interchangeable Slits Upgrades are available for “HR” optical benches to allow more application flexibility. High Scattering samples can be measured with the smallest slit for highest resolution and weak Raman can be measure with a larger slit to allow for increased light throughput.
