Have I selected the right laser for my Raman experiments?

November 20, 2019

Thanks to rapid technology advancements in recent years, Raman Spectroscopy has become a routine, cost-efficient, and much appreciated analytical tool with applications in material science and in-line process control for pharmaceutical, food & beverage, chemical and agricultural industries. Improvements in laser technology, detectors (CCDs and InGaAs arrays), and spectral filters (VBG-based notch filters), along with developments of new schemes for signal generation and detection, have aided Raman instrument manufacturers in overcoming the challenge of weak signals which has accelerated instrument development and market growth. In this white paper, we discuss important performance parameters to consider when selecting the laser for Raman spectroscopy experiments.

Blink and You Miss It—Catching Fleeting Catalytic Intermediates by High-Speed 785 nm NIR Raman Spectroscopy

April 25, 2017

It is only in the last two decades that Raman spectroscopy has begun to realize its potential as an almost universally applicable analytical technique from materials and life sciences applications to point of care analysis. This is primarily thanks to the availability of compact laser sources, high sensitivity cameras and high resolution compact spectrometers. In this application note the use of a stable high power NIR 785 nm laser is shown to be critical in achieving high time resolution and high signal to noise ratios while allowing for both fast and slow processes to be captured simultaneously.
