The Nikon LC15Dx scanner has demonstrated laser scanning in the accuracy range of tactile inspection.
The company claims the LC15Dx is a viable alternative to a tactile probe for an increasing number of high precision CMM applications including molds, small turbine blades, medical devices and other complex geometry.
Thanks to new solid state laser scanner technology, an innovative calibration method and Nikon lens, the LC15Dx achieves a probing accuracy of 2.5um (0.0001in) multi-stylus test accuracy of 6um (0.00024in) in tests comparable to EN/10360-2 and -5.
A unique thermal stabiliser inside the scanner body eliminates the uncertainty and delay caused when the laser scanner is used before it has reached operating temperature.
Probe tip compensation errors are also eliminated by using non-contact triangulation between the laser source, workpiece and CCD sensor to measure the surface of the workpiece directly.
A greater range and mix of surface materials, finishes, colors and transitions can be measured more efficiently without user interaction, manual tuning and part spraying.
Nikons third-generation Enhanced Scanner Performance (ESP3) technology maintains accuracy, speed and data quality by intelligently adapting the laser settings for each measured point in real-time.
Unwanted reflections are neutralised by an advanced software filter while changes in ambient light are absorbed by a high grade daylight filter.
This means manufacturers can gain a full appreciation of the dimensional quality of their products without compromising cycle times.
