Information the Equipment Can Provide

The Zygo interferometer is a laser-based tool to measure large area topography of flat samples.  The system allows for rapid scanning of up to 6″ diameter samples at the lowest resolution. The He:Ne laser allows for the measurement of height changes of up to 632 nm over small distance.


  • Rapid, noninvasive, large-area, topographical measurements of flat substrates
  • 120-micron lateral resolution at the lowest magnification, 20-micron resolution at the highest magnification
