Non-contact Scanning Probe
Jul 2014
Hexagon Manufacturing Intelligence
NORTH KINGSTOWN, R.I., July 15, 2014 — The HP-O Probe from Hexagon Metrology is a non-contact optical scanning probe that delivers force-free measurements on deformable parts and surfaces.

The device is based on frequency-modulated, interferometric optical distance measurement and is not affected by ambient light. It has a measurement range of up to 20 mm and repeatability of under 0.3 µm and has an acceptance angle of &plusmin;30 °. The probe can measure difficult-to-access features at a scanning speed of 1,000 points per second for rapid throughput.

The probe can be used to inspect metallic or sensitive part surfaces with mirror-like or polished finishes, eliminating the need to spray a part’s surface or measure blisks, blades, gear profiles and flank lines.

The study and utilization of interference phenomena, based on the wave properties of light.
The science of measurement, particularly of lengths and angles.
