Products: IntelliCal Spectral Calibration System
Spectral Calibration Made Easy
Precise wavelength and intensity calibration plays an important role in spectroscopy applications.
Princeton Instruments patented IntelliCal® is the industry’s only easy-to-use wavelength and intensity calibration system. What used to take hours or even days can now be completed in a matter of minutes with dramatically improved accuracy. IntelliCal includes dual Hg/Ne atomic emission and LED-based, NIST traceable intensity calibration light sources.
Intellical's benefits include:

Advanced CCD Cameras and Imaging Spectrographs Facilitate Acquisition of Novel Femtosecond Stimulated Raman Spectroscopy Data To Improve SERS Biosensors
Accurate characterization of surface-enhanced Raman spectroscopy (SERS) biosensors, fluorescent dye molecules that hold great promise for in vivo bioanalyte detection, can often be quite difficult as the overwhelming isoenergetic fluorescence signal typically makes it challenging to measure resonance Raman cross-sections for the molecules. To overcome this obstacle, researchers at the University of Minnesota in Minneapolis recently utilized etalonbased femtosecond stimulated Raman spectroscopy (FSRS), a technique designed to acquire a stimulated Raman signal without strong fluorescence or interference from signals resulting from other four-wave mixing pathway
