Kaiser Raman PhAT probe

The no-touch, focus-free solution for Raman lab or process measurement

With the Kaiser Raman PhAT probe, you get reproducible, representative, focus-free, quantitative Raman measurements, while measuring heterogeneous solids from a distance by making mm-scale volumetric measurements. The probe illuminates a large surface area and eliminates the need to align the probe for surface roughness.  Improve your process control and gain efficiency that comes with getting a representative measurement of your solid in less analysis time.

Both insertion and non-contact sampling options are available for the PhAT probe head to enhance sampling flexibility. The PhAT probe is constructed of a stainless-steel body which allows for cleanability between batches when used in a manufacturing environment.
