RP50 Raman Probe

The fibre-coupled RP50 Raman probe is designed to operate with the HES2000 spatial heterodyne spectrometer.

Operating at a 25mm standoff distance from the enclosure aperture, these probes facilitate non-destruction interrogation of target samples to capture material-specific Raman spectra.

The specifications given are for the standard RP50. Please get in touch for customisation options, including alternative Raman excitation operating wavelengths.

Probe performance comparison between the 785nm RP40 and the RP50 probes

The new RP40 probe requires a 0.5s exposure to get a Paracetamol spectrum compared to the RP50 probe, which requires a 2.5s exposure to get the same performance level. The RP40 is four times better than the RP50. Note: With the RP50, overexposure is seen at 2.5s, so it can only be exposed up to 1.9s (less performance).
