SURFACE STEP HEIGHT MEASUREMENT | DEPTH & THICKNESS

The chromatic confocal technique offers the best accurately measures step heights from 60nm to 20mm. The advantage of the technique to accurately measure thickness lies on the fact that chromatic confocal is not influence by large change in reflectivity or texture as sometime seen when going from a coating to its substrate. Thickness of an optical transparent layer can also be measured with similar resolution and range (> 7μm).
