Unlike tactile measurement methods, the acquisition is completely non-contact. Sensitive, coated, or high-precision surfaces can thus be inspected without mechanically influencing the component.<\/p>\n
Dynamic Interferometry\u00ae for vibration-insensitive measurements<\/h3>\n
At the heart of the NanoCam HD is the patented Dynamic Interferometry\u00ae Technology from 4D Technology<\/strong>. The phase information required for a complete surface measurement is captured simultaneously instead of requiring multiple sequential exposures.<\/p>\n A measurement can thereby be done in less than 100 microseconds<\/strong> take place. Vibrations, air currents, and other environmental influences have significantly less time to affect the measurement result.<\/p>\n Therefore, the NanoCam HD can also be used outside of a traditional vibration-isolated measurement laboratory \u2013 for example, directly in production environments or in automated testing stations.<\/p>\n With a vertical resolution up to 1 \u00c5<\/strong> the NanoCam HD enables the quantitative analysis of very small surface structures. In addition to classic roughness measurement, three-dimensional surface topographies can be captured and different areas of a surface can be compared with one another.<\/p>\n The evaluation supports surface parameters according to ISO 25178<\/strong> and thus enables a standardized quantitative characterization of the measured surfaces.<\/p>\n A special strength of the NanoCam HD is the combination of high vertical resolution and a comparatively large measurement field. This allows larger areas of a surface to be captured in a single measurement.<\/p>\n This reduces the effort compared to methods in which a surface has to be scanned point by point or line by line, making the system particularly attractive for fast inspection and quality control tasks.<\/p>\nsurface roughness down to the angstrom range<\/h3>\n
