White Light Interferometry vs. Confocal Microscopy in 3D Optical Surface Profilometry
High-Precision Optical Metrology in Modern Manufacturing Surface finish evaluation is critical for high-performance mechanical components, micro-electronics, and polishedoptical molds. Achieving nanometer-level vertical resolution requires non-contact optical profilometry, eliminating thephysical scratch damage caused by traditional diamond-stylus profilers. How Does White Light Interferometry Achieve Sub-Nanometer Resolution? White Light Interferometry achieves sub-nanometer vertical resolution by splitting a broadband […]
