IPS specializes in Wavelength Stabilized Lasers
IPS supplies over 70% of all Raman spectroscopy system integrators with their diode based Raman excitation sources, and is the “Gold Standard” for high performance wavelength stabilized lasers.
Raman spectroscopy is a vibrational spectroscopy method that has successfully been used in the lab for some time, and has recently gained traction commercially as an affordable and accurate way to get qualitative and quantitative information instantly without destroying the sample. Raman spectroscopy can also be used to analyze aqueous solutions removing tedious sample prep required for other analytical techniques.
