The chromatic confocal technique accurately measures step heights up to 25mm with depth resolutions down to 2.7nm. The chromatic confocal technique is a non-destructive method for the measurement of step heights with no influence from on accuracy reflectivity or material change between coating and substrate. Thickness of an optical transparent layer can also be measured with similar resolution and range (lower limit of about 7µm).
