Standard and Stand-off Raman Probes
When a sample is large, in a hazardous or high-temperature environment, or for any reason, difficult to bring to a spectrometer, a probe provides the ideal solution for getting real-time observations.
As with Raman spectrometers, a Raman probe is used to measure the inelastic scattering of light from a sample. Raman scattering is produced when the energy levels of photons are shifted up or down as a result of excitation by a monochromatic source (usually a laser). The change in vibrational frequency is used to determine the composition of a target substance.
A Raman probe focuses the laser on the sample, collects the scattered light and feeds it back to the spectrometer.
Our Raman probes are ideally suited for coupling with our range of high etendue HES spectrometers. We currently offer two probes: the Standard Raman Probe for close or contact measurements, or the Stand-Off Raman Probe, capable of making measurements from a distance of up to 3 metres.
