The RamanProbeTM

The original RamanProbe (TM) laboratory probeEfficient focussing and filtering optics are incorporated into the remarkably compact RamanProbe (4" long x 0.5" diameter), resulting in a versatile sampling tool for the laboratory. The focussed design makes it ideal for analysis through glass and plastic, as well as for measurement of neat solids and surfaces. The standard 5 m cable is integrated directly into the probe; longer fibers and cable extensions are available as options.

The RamanProbe is available for select excitation wavelengths in the visible and near-IR. The patented design (US 5,112,127) completely filters Rayleigh scattering with an attenuation of 108. The probe also eliminates background signals arising in the fiber optic cables for optimum data quality even over 500 feet of fiber. The high Rayleigh attenuation also negates the need for additional filtering in the spectrograph. In effect, our Raman probe can be coupled to any spectrograph, detector, and laser to create a complete Raman system.

Don't accept inferior imitations! Only the InPhotonics' RamanProbe offers complete optical filtering, sharp cut on prior to 250 cm-1, compact size with colinear fibers, and a choice of fiber sizes to match any laser/spectrograph combination. We also offer technical and applications support for the life of the product -- ask us for references!
