RPB Raman probes
RPB Series Fibre-Coupled Raman Probes, 360–1064 nm
Fully solidified (cured) optical probes that carry the excitation laser to the sample and collect the Raman return into a fibre spectrometer, at twelve excitation wavelengths from 360 to 1064 nm. Three body styles share the same 7.5 mm focal length; the -L versions at 532, 639, 785, 830 and 1064 nm reach 100 cm⁻¹.
