Sheet metal surface measurements
The sheet metal forming has high requirements on the micro structures as well as on the waviness of the raw material. Parameters as Wa with evaluation length of 50 mm and tolerances of parts from a micrometer require the combination of an fast scanning process with, an nm accuracy and a dedicated software with all necessary algorithms implemented.

Wa (0.8 mm) = 0.41 µm (average out of multiple profiles)
Wsa 1 – 5 = 0.25 µm (average out of multiple profiles)
The smartWLI prime combines the necessary resolution and accuracy with an high speed 3d scanning process. With single scans below 2 s and scanning and evaluation of an 50 mm segment in less than 1 minute it fullfils the requirements. With nm resolution and the ability to measure and analyse multiple profiles parallel it provides much more significant results than any stylus instrument could provide.
