Optical Gaging Products (OGP®), a division of Quality Vision International (QVI®), introduced its RP1500 Rainbow Probe optical measurement sensor to the metrology marketplace.
Innovative OGP Rainbow Probe technology provides high resolution non-contact measurement by analyzing the optical spectrum of reflected light to measure surface height changes. Rainbow Probe can measure where other sensors cannot, easily characterizing transparent, translucent, fragile, liquid or easily deformable surfaces. A range of probes are available, each with a unique measuring range, working distance, axial resolution, accuracy, and spot size.
