RPB Laboratory Probe
The
RPB Raman fiber optic probe is a breakthrough for routine laboratory Raman
spectroscopy. A modified design based upon the patented RamanProbeTM
optical layout has resulted in drastic cost-reduction with limited performance
tradeoff. At a retail price of $2,950,
the RPB is the clear cost/performance winner among laboratory Raman sampling
probes. 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 105 µm excitation fiber and 200 µm
collection fibers can be coupled to most laser/spectrograph combinations.
Custom configurations are available for high-volume applications.
