Metrology Laser-based thickness measurement
The most important new features of alpha.ti 4.0 include temperature-independent measuring accuracy between 10 °C and 40 °C ambient temperature (0.01 % of the measuring range), flexible measuring ranges with tool-less sensor replacement without needing adjustment, as well as the quick-exchange sensor panes and invisible air knives to keep the optical paths clear. Standard measuring ranges are 15 mm, 25 mm and 40 mm. The system is available as C- or O-frame, in both cases the measuring operation can be traversing or using a fixed measuring track.
Due to the simplicity and compactness of alpha.ti 4.0, it is possible for the first time to use the system as an off-line system for laboratory measurements. For this purpose, a sample scanning mode is available to deliver either a single measurement or a composite area profile of an entire sample section efficiently. Future software options allow alpha.ti 4.0 to grow flexibly with new demands, for instance for data filtering or data aggregation in the context of Industry 4.0.
