OGP® (Optical Gaging Products) offers enhanced measurement capability with its Feather Probe™ micro-metrology sensor.

Feather Probe is one of the many specialized sensors available in the OGP multisensor toolbox. This tactile probe uses resonance as its trigger mode. Feather Probe tips can be as minimal as 100 microns in diameter, and exhibit trigger forces well below 1 milligram. These characteristics make Feather Probe perfect for measuring extremely small features, as well as fragile or easily-deformed features. Typically protected behind a cover when not in use, Feather Probe styli can be automatically deployed into the measurement area whenever needed, and retracted out of the way when not in use.
