Raman Probes


What are Raman Probes?

Raman probes are laser-based devices, utilizing optical fibers to deliver of an excitation laser wavelength to a sample and collecting the return signal, used in hazardous or high-temperature environments, which are unsuitable for traditional Raman spectrometers.

Raman probes can provide increased flexibility and higher throughput with the use of fibers and interchangeable filters and probe tips for example. Similar to traditional Raman spectrometers, Raman probes measure the inelastic scattering of laser light off of a sample. The Raman scattering comes as a result of shifted energy levels of photons. Analysis of this ‘Raman shift’ determines the composition of the target substance.

Our Raman Laser Products

RPMC Lasers is proud to offer an ultra-high throughput integrated Raman probe. These novel devices includes an integrated wavelength stabilized laser source with Raman filter packs, beam shaping optics, and high-efficiency Raman spectra collection optics. The probe interfaces with any fiber coupled spectrometer and simplifies operation and set-up.

This Integrated Probe incorporates our wavelength stabilized hybrid external cavity laser (HECL) with a proprietary optical design to offer unmatched performance (typically 3x -5x over traditional probes) at a reasonable price.

RPMC’s Integrated Raman probes also come complete with a UL/CE, and IEC compliant control box providing a variety of power control options including TTL, analog, and USB.
