The RamanProbe IITM
RamanProbe II is a versatile fiber optic probe for immersion analysis based
on the patented optics of the original RamanProbe. The 8" long body and
removable sleeve enable the probe to be immersed directly in solutions for true
in situ analysis. The focal distance is selectable to optimize the measurement
of dark or turbid solutions.
The standard immersion
sleeve is made of stainless-steel with a sapphire window. Overall, the probe
is 5/8" in diameter, small enough to fit inside typical laboratory-scale
vessels. The sleeve can be quickly removed for routine measurement of neat solids
or samples in bottles.
