Measuring surface roughness and surface texture of machined components provides critical data that can be used to control and improve performance. Functionality ranging from appearance to adhesion to fit all benefit from a thorough understanding of the 3D surface texture of critical surfaces. Roughness measurement also aids maintenance personnel. Measuring surface roughness over time helps to guarantee functionality as a component wears and may indicate ways that wear can be reduced or eliminated.
In the world of optics, measuring and controlling roughness on blanks and substrates leads to proper adhesion and finish during coating operations. The roughness of coated surfaces can also be measured to indicate the effectiveness of the coating and polishing operations and to verify the performance of the final article.
4D Optical Surface Profilers measure surface roughness in shop floor environments, without vibration isolation. The compact NanoCam HD measures smooth and super-smooth surfaces and can be used in situ in polishing equipment, on gantries or robots, or directly on large components.
Custom Solutions bring the power of roughness measure to roll-to-roll (R2R) manufacturing of flexible electronics, for real-time monitoring and control of roughness to less than 0.5 nm rms.
