TR Scan Compact WLI

High precision non-contact surface measurement


TR Scan WLI

The new 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.

  • Non-contact
  • Small footprint
  • Measuring range 400 µm
  • Resolution 0.1 nanometer
  • Extremely easy to use
  • 2.5x and 5x Michelson type optics for a wide field of view
  • Exchangeable optics, or mounted on a carousel
 

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.
