TR Scan Compact WLI

High precision non-contact surface measurement

The TR Scan Compact WLI range allows measurements on any type of material with sub-nanometric resolution.
With its simplicity of use and small size it integrates easily in a lab environment and permit to realize quick and simple measurements.

WLI (While Light Interferometry) technology combined with a piezo motor allows extremely fast measurements.
The table allows manual movement with workpieces weighing up to 5 kg.
Motorized tables are available as an option to extend the X&Y measuring range.
