Raman Process Probes


Out of stock

With an extension tube design to protect probe optics from the high temperatures of process environments, RPP Raman process probes help bring Raman spectroscopy to industrial applications. The RPP’s pressure-tight, stainless steel extension tube can be immersed in process streams and hostile environments without affecting the probe’s Raman-optimized filtering and focusing optical design.

RPP probes are available for 532 nm, 785 nm and other excitation wavelengths, with FC and SMA 905 connectors for excitation and collection fibers. The probes are rated to 3000 psi and can be heated to 500 °C.

  • Process-ready design – extension tube separates optics from high temperature environments
  • In situ measurements – immerse tube in process streams without affecting probe optics
  • Short working distance – choice of working distance from 0.5 mm to 6 mm
  • Deep laser line blocking – OD 8 attenuation of the Rayleigh line
