RP40 Raman Probe

A leap forward for Raman technology

The RP40 represents a substantial improvement in probe technology, facilitating the non-destructive interrogation of target samples, delivering clear, sharp results over significantly reduced exposure times compared to most standard probes, including the RP50.

These probes are ideal for application in various environments, including pharmaceutical, process control, and Security and defence.

Product Specifications

RP1000 Raman Probe for Stand-Off Measurements

The RP40 operates at a 15 mm distance from the enclosure aperture to capture material-specific Raman spectra.

This fibre-coupled probe is designed to operate with the HES2000 spatial heterodyne spectrometer.

The specifications given are for the standard RP40. Please get in touch for customisation options, including alternative Raman excitation operating wavelengths.

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

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