MESA Flatness Measuring Tool

The MESA Flatness Measuring Tool provides the flatness measurements that are required on a increasing number of surfaces. It provides the feedback to grinding, honing, polishing, lapping, and super-finishing processes that permits these machines to produce more consistent and reliable parts. It provides information about these surfaces that allows you to improve and refine your process to maximize throughput and yield. The MESA provides accurate, repeatable, fast, cost-effective, and safe flatness measurements for a wide range of surface roughness and departures. MESA can be easily configured as a manually-operated system or is available fully automated for production floor operation.

Based on years of Zygo experience in precision metrology, MESA bridges the gap between interferometric and geometric optical metrology thanks to its innovative use of diffractive optics. MESA extends flatness measurement capabilities while maintaining the inherent advantages of interferometric measurements. These advantages include fast 3-D surface analysis, high spatial measurement resolution, excellent measurement repeatability and reproducibility, and a large working distance to the test surface. Most importantly, MESA extends the range of interferometry without relying on expensive or exotic components.

MESA employs state of the art diffractive optics to capture the entire surface of your part in one "shot." In less than 2 seconds, a 3-D image of your part's surface is displayed along with any number of numeric results that you choose to characterize the surface.
