Raman Immersion Probes


Out of stock

Our RP2 and RPR Raman immersion probes are ideal for in situ measurement of clear or turbid solutions. The probes are available for 532 nm, 785 nm and other excitation wavelengths, with FC and SMA 905 connectors for excitation and collection fibers.

RP2 lab probes are distinguished by a stainless steel immersion sleeve that’s adjustable for different working distances. RP2s can be heated to 200 °C but are not designed for high-pressure use. For high-pressure applications we offer the RPR probes, which are rated to 1500 psi and can be heated to 200 °C.  RPRs are best suited for process environments, with robust probe materials, chemically resistant welded seals and other industrial-grade components.

  • In situ analysis – immerse probes directly into solutions for real-time measurements
  • Lab and process versions – probe designs for variety of immersion environments
  • Adjustable working distance – change working distance for clear or turbid solutions
  • Deep laser line blocking – OD 8 attenuation of the Rayleigh line
