The eXtreme TE cooler detector upgrade lowers the temperature of the CCD to 30 degrees below ambient and increase instrument S/N drastically by reducing noise over 80% at long exposures. This 2-stage eXtreme TEC upgrade improves low light measurement quality and detection limit capability for Raman, Fluorescence, and other weak light emission applications.
Thermoelectric detector cooling improves the stability of the detector for lengthy measurements where thermal noise can distort and override signal. In order to achieve such low temperatures the 2-stage eXtreme TEC add-on includes a new sealed and isolated detector enclosure with specialized heat sink and air flow design for added stability and cool operation.

Choosing a Raman Spectrometer System’s Excitation Wavelength
When choosing a Raman instrument, one of the primary concerns is the wavelength of the laser that is integrated into the Raman spectrometer system.
How do I choose a Raman laser frequency for my Raman spectroscopy application?
A samples Raman signature and the peak position is related to the samples unique chemical structure and is independent of the excitation wavelength, so the molecular fingerprint will be the same regardless of the excitation laser wavelength.
Different laser frequencies provide specific strengths and weaknesses allowing a user to optimize the measurement of different samples by their choice of Raman laser. The three most popular Raman spectrometer wavelengths are 532nm, 785nm and 1064nm.
*Most popular system for price and performance

Raman Spectra of Minerals – Fluorite
Raman spectroscopy is being used more and more in the analysis of rocks and minerals. Raman is very sensitive to end-member functional groups like -OH and -CO2 and is well suited for silicate and carbonate minerals. Raman can identify minerals that NIR or other techniques may be blind to and can even identify different forms of carbon.
