The RamanProbe IITM

RamanProbe II, shown with immersion sleeve removed.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.
