TMS-100 TopMap Metro.Lab - Features

Polytec’s TopMap Metro.Lab is an affordable, high-precision, non-contact topography measurement system designed to characterize flat and curved surfaces. Incorporating a scanning white light interferometer, the Metro.Lab can measure flatness and general topography with 20 nanometer resolution and determine parallelity of two or more surfaces separated by as much as 70 mm.

Key Features

• Non-contact topography measuring interferometer
• Measurement on surfaces near steep edges (e.g. drilling holes) is possible due to telecentric optics
• Increased flexibility due to large 70 mm z-dynamic range
• Fast measurement over large field-of-view
• Large 80 mm x 80 mm field-of-view possible with simplified stitching (enhanced version)
  

Curvature and Flatness Mesurement Made Simple and Efficient

The TopMap Metro.Lab is a complete measurement station for characterizing the topography of large surfaces without contact. Complex parts can have many precision flat and curved surfaces that must be measured  and compared. The Metro.Lab’s wide field-of-view and large z-dynamic range are critical advantages when fast throughput is desired. By combining increased throughput, simple operation, precision measurement and an affordable cost, Polytec is changing traditional contact metrology.

With a large z-dynamic range of 70 mm, the measurement of flatness, ripple and parallelism is simple even under traditionally difficult circumstances such as comparing the top and  bottom surfaces of a blind hole. Classic surface parameters currently measured with touch probes can also easily be investigated with the Metro.Lab. Since the complete measurement area is captured in one measurement run instead of composing it from individual lines, measurements are often completed in just a few seconds.
 
Scanning white light interferometry enables precision non-contact non-destructive measurement and analysis of hard or soft, robust or delicate surfaces. For test objects larger than the available field-of-view of the model Metro.Lab, an enhanced model is available that allows for a shift of 50 mm x 50 mm (in x or y direction). The total surface is then assembled from the individual measurements by the stitching software. This allows for significantly larger measurement areas of up to 80 mm x 80 mm. Due to an excellent cost/performance ratio, the TopMap Metro.Lab is an attractive solution even when test sample volume is low.

The TopMap Metro.Lab is equipped with the user-friendly TMS Software from Polytec that provides all essential control and analysis tools. Its open software architecture allows for custom programming of routinely repeated measurement tasks e.g. with Visual Basic® or for the customization of the user interface.
