RamanProbe
The original RamanProbe laboratory probe. Efficient focussing and filtering optics are incorporated into a remarkably compact design (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 patented design (US 5,112,127) completely filters Rayleigh scattering with an attenuation of 108, eliminating background signals from fiber optic cables for optimum data quality over long fiber runs.
