The Tropel FlatMaster provides industry-leading performance of surface form measurements for precision-component manufacturers. Our non-contact optical technique records the entire surface in seconds.

The Tropel FlatMaster MSP (Multi-Surface Profiler) is a frequency stepping interferometer that provides fast and accurate metrology for semiconductor wafers up to 300mm in diameter.  In seconds up to 3 million data points are collected with sub-micron accuracy enabling total thickness and flatness characterization over the entire surface.

The Tropel UltraFlatTM 200 Mask System was designed specifically for the photomask industry. It delivers the lowest measurement uncertainty for ever-tightening mask flatness specifications. Shrinking device features require not only flatter wafers, but flatter masks.
