TecScan’s R-Theta Manual Inspection Scanner is a two-axis scanner designed for circular inspections. Equipped with encoded radial (R) and rotational (θ) axes, this scanner is designed to perform ring-shaped raster scan inspections from a single attach point. The R-θ Manual Inspection Scanner has indexing capabilities on the linear R axis to perform raster scan easily. It is also equipped with an articulated probe support for an optimal contact between the probe and the inspected surface.
