RamanProbe LC - Fiber Optic Coupled Low Cost Raman Probe for Laboratory Applications



Request for information




The RPB Raman fiber optic probe is a breakthrough for routine laboratory Raman spectroscopy. A modified design based upon the patented Standard RamanProbeTM optical layout has resulted in drastic cost-reduction with limited performance tradeoff. The RPB is available for three excitation wavelengths: 785, 633, and 532 nm and can be coupled to a variety of spectrograph designs. Optical filtering of 106 offers efficient attenuation of the Rayleigh line for background-free spectra. The probe is lightweight and compact, and has a manual safety shutter (with built in calibration standard)† to shield the user from the laser light. As with our standard RamanProbeTM, the RPB can be used with the compact sample holder for routine measurement of liquids and solids. The 90 Ám excitation fiber and 200 Ám collection fibers can be coupled to most laser/spectrograph combinations. Custom configurations are available for high-volume applications.
