The RamanProbe IITM
The
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.
