Non contact sensors

Lasers Offer Viable, Noncontact Alternative to Touch Probes:

Specialized optics and automatic, real-time calibration make Nextec’s laser systems a viable alternative to mechanical touch probes for high-volume inspection applications involving complex geometry and tight tolerances. NEXTEC non contact sensors unlock the full potential of the inherent speed of laser measurement. By nature, measuring part geometry by tracking a beam across the part surface is faster than taking a series of points with a touch probe, especially for non-prismatic parts with complex, freeform geometries. Such components often require complex motion to keep the probe in constant contact with the surface, not to mention special fixturing that can be expensive and time-consuming to machine and set up. Minute, sculpted features like blade edges can be particularly problematic, even for the smallest-diameter touch probes.



Non-contact sensor role can be both major or minor – depends on application:


• Major role – Automatic movement compensation along with the optical beam, when sensor defines the movement path for the Motion Controller
• Minor role – Motion Controller works in CNC mode and movement path is defined by the user
Non-contact sensors, full integration with rotary stage and Renishaw motorized head equipment, allows us to provide advanced inspection solution and to extremely shorten inspection cycle time. Nextec sensors are not sensitive to the environment lighting, shading ; steady and durable in collision. Nextec software includes unique functional and algorithmic calculation methods and fully compatible with all the rest Nextec equipment.
