A Tactile Probe into the Microscopic World: An In-depth Analysis of Stylus Profiler Technology and Its Frontier Applications
In cutting-edge technological fields such as semiconductor manufacturing, precision optics, new materials science, and micro-electromechanical systems (MEMS), the precise control and measurement of material surface topography have become the cornerstone for determining product performance and yield. As we explore scales descending from millimeters and micrometers down to the nanometer level, how can we accurately "touch" and quantify the "topography" of this microscopic world? Among the many surface metrology techniques, the stylus profiler, with its direct, reliable, and high-resolution physical contact measurement method, remains an indispensable core tool. This article will provide an in-depth analysis of the stylus profiler's working principle, its core sensor technologies, key performance indicators, and explore its profound applications in modern industry and scientific research.
