Watchmakers rely on CSI Coherence Scanning Interferometry
The surface quality of watch and clock parts is verified through measurement precision and repeatability of CSI Coherence Scanning Interferometers (also known as white-light interferometers). Check geometrical tolerances on watch components, measuring form parameters like flatness, parallelism or step-height in watchmaking.
TopMap areal scanning white-light-interferometers deliver fast, complete, and high-resolution measurement data on micro parts. In contrast to other optical measurement technologies (e.g. fringe projection or focus variation), TopMap optical profilers measure reliably on both rough and optically smooth surfaces.
Flatness, thickness and parallelism of watch components
Let's take a closer look over a watchmaker’s shoulder to see how white-light interferometers support their precision engineered surfaces. Evaluate steps, flatness, and parallelism on adjacent surfaces on watch parts and other precision engineered parts. A minute wheel drive from a watch, shown as 3D topography profile. To verify the manufactured quality, the surface roughness on the inclined area, which is approximately 100 x 300 μm2 ,must be measured. Tactile measurement methods would cause problems due to the geometry of the measurement area. On the other hand, optical techniques such as white-light interferometry allow the topography to be captured within a matter of seconds.

Fitting surface profiler
Micro Profiler
Micro.View profiler systems are optimized for measurements with sub-nanometer resolution. With focused optics and high vertical resolution they enable detailed analysis of microstructures, surface finish and material distribution where even the smallest deviations matter.
Macro Profiler
Pro.Surf inspects flatness, step height and parallelism on large parts and multi-part trays — non-contact, in seconds. No-crash telecentric optics measure even into bores, with the precision and repeatability production demands.
Roughness Tester
The Roughness Tester is our entry Micro.View system and the most cost effective way to get started into the 3D surface roughness measurement. Step from R to S parameters.
