Metrology Sensor for Small Features Compensates for Environmental Effects

OGP (Optical Gaging Products), a division of Quality Vision International (QVI), offers its Feather Probe micro-metrology sensor, a tactile probe that uses resonance as its trigger mode. Probe tips can be as small as 100 microns in diameter and exhibit trigger forces well below 1 mg. These characteristics make this probe suitable for measuring extremely small features as well as fragile or easily-deformed features, the company says.

One significant enhancement to this probe is Dynamic Resonance Mode, which enables the controller to constantly monitor probe resonance to detect potential environmental effects such as temperature, air motion and vibration. When such an effect is detected, the controller dynamically adjusts the probe resonance to compensate, maintaining accuracy.

The Feather Probe is also equipped with an improved deployment mechanism, which moves the probe into and out of the measurement area, retracting the probe out of the way when not in use. It seats securely into a robust kinematic mounting system, ensuring measurement repeatability.

The sensor is compatible with QVI’s Zone3, MeasureMind 3D MultiSensor and VMS metrology software platforms.
