2D & 3D non contact surface Metrology
White light interferometry is a high-resolution, non-contact technique used to measure surface profiles by analyzing the interference patterns produced when white light interacts with a sample surface. A broad spectrum of light is split into two beams, one reflected from the surface and the other from a reference mirror. The interference between these beams depends on the optical path difference, which is influenced by the height variations of the surface. Due to the short coherence length of white light, clear interference fringes only appear for small height differences, allowing precise measurements of surface features. This technique is widely used for 3D surface profiling, step height measurements, and surface roughness analysis.
