Mk II Filtered Probe Head

Kaiser's Mk II probe is a research Raman flexible probe head capable of measuring depolarization ratios using an optional Kaiser-supplied polarization accessory. Independent control over the excitation and collection polarizers allow maximum flexibility when conducting polarized Raman experiments.

The Mk II probe head allows a wide range of optics to be attached. Non-contact optics with working distances of 0.1 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. The Mk II probe head also serves as a stable interface for the Raman Microprobe and CDRH class 1 sample compartment (RXN-ASC) options.
