Kaiser Raman PhAT probe
The no-touch, focus-free solution for Raman lab or process solids measurement
For solids and semi-solids analysis, the PhAT probe reigns supreme. Its state-of-the-art, stainless-steel probe design produces representative, focus-free, quantitative Raman measurements. The PhAT probe illuminates a large surface area and eliminates the need to align the probe for surface roughness.
A large excitation spot (6 mm) and multiple collection fibers in the PhAT probe achieves heterogenous solids sampling in both the axial and lateral dimensions. In doing so, it provides information on deeper layers in addition to the surface, which is highly useful for measuring heterogenous solids such as tablets, capsules, food solids, and polymer beads. To enhance sampling flexibility, both insertion and non-contact sampling optics are available for the PhAT probe.
