Product Overview - Raman Spectrometers

InPhotote portable Raman system VERAX mid-range laboratory spectrometer RS2000 research grade spectrometer InPhotonics offers rugged Raman systems based on our proprietary spectrograph designs. We use frequency-stabilized lasers that provide consistent output and linewidths better than the spectrograph resolution. Only TE-cooled photodector arrays are offered as detectors for the high sensitivity necessary for Raman spectroscopy. All of our spectrometers are dedicated to fiber optic measurement with our own RamanProbeTM line of fiber optic sampling probes for flexible yet efficient signal collection.

The RS2000 research-grade spectrometer provides high resolution and full spectral range in a permanently-aligned benchtop system. The InPhototeTM and VERAX offer the "fingerprint region" with ample resolution and sensitivity in compact packages. InPhotote1064 provides more options to the excitation source.Please consult the individual product pages for more detailed descriptions.
