Rainbow Probe

Rainbow ProbeRainbow Probe™ is an electro-optical device that measures surfaces without contact by analyzing changes in the optical spectrum as a function of part-to-probe spacing as it scans.

White light is emitted from the rainbow probe, reflected light from the part strikes a detector inside the probe. Shifts in the optical spectrum as a function of probe-to-surface spacing are output as data points as the probe scans a surface. The probe’s small spot size enables Rainbow Probe to access small features, and its on-axis measuring technique allows it to measure recessed features that may not be accessible by other means.

Rainbow ProbeRainbow Probe is available as an option on SmartScope® Quest™, SmartScope ZIP® and SmartScope Flash™ systems.
