Rainbow Probe

High Resolution, Non-Contact Optical Sensor for Surface Measurements

Rainbow 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. Rainbow Probes easily measures transparent, translucent, fragile, liquid or easily deformable surfaces and are a mounted in mechanical deployment mechanisms so they can be retracted when not in use. The Rainbow Probe offers:

Measures where other sensors cannot – Rainbow Probe easily measures transparent, translucent, fragile, liquid or easily deformable surfaces

Dual measuring modes – Select distance or thickness measuring mode

The right probe for your application – A range of CL-series and RP-series probes are available, each with a unique measuring range, working distance, axial resolution, accuracy, and spot size

Multisensor integration – Integrates into automatic measurements with other sensors on OGP measurement systems
