The MR Probe filtered probe head has been developed for optimal performance with all the Raman analyzers in the RAMANRXN SYSTEMS™ suite. It utilizes a state-of-the-art design to provide high signal-to-background measurements at any length of optical fiber. The fixed-focus design of each removable immersion optic provides long-term measurement stability along with superior signal-to-background measurements unlike traditional probes. This fiber-optically coupled probe is both compact and lightweight, which maximizes sampling opportunities.

The MR Probe is versatile enough to accept a wide range of optics. Noncontact optics with working distances of 0.3 inches to 17 inches can be used to measure through windows, bottles, or simply at a convenient distance from a sample. Immersion and insertion optics are available for reaction vessels, automated laboratory reactors, or process streams.

All MR Probes utilize a single fiber for excitation and another for collection. For laboratory equipment, this provides a robust interface and sampling versatility. For process equipment, single fibers allow reduced cost for long runs of fiber as compared to multi-fiber collection designs. Single collection fibers also permit simultaneous multi-channel operation on a single analyzer. Standard telecommunication fiber diameters (<100 microns) are used to increase mechanical stability. This results in fewer broken fibers, increased safety, and lower maintenance costs.
