NRS-4500 Raman Spectrometer

In Raman spectrometry, sample preparation is generally considered to be much easier than for infrared spectroscopy and unlike FTIR microscopy, Raman offers greatly improved spatial resolution.
As a result, the use of Raman spectrometry is rapidly spreading as the analytical technique of choice for materials analysis. One of the factors which has previously held back the adoption of laser Raman instruments is the skill set required for optical adjustment, measurement optimization and data analysis. The NRS-4500 will change the way Raman is used for so many different applications from QA, to academic teaching, to cutting edge research.

Laser choices for improved fluorescence rejection

As with other Raman systems, we can utilize laser wavelengths of 785nm and up to 1064nm. Selecting optional excitation laser wavelengths is only one of the ways JASCO minimizes fluorescence interference.

High Speed imaging Raman system - QRI -

The QRI consists of high speed / high accuracy stage and high speed data aquisition in CCD detector and it makes it possible to shorten amount of analysis time dramatically. In addition, EMCCD is an attractive option for high speed weak light measurement.
