GelSight® Modulus™
The SLR-style design with swappable optics brings unmatched measurement capability to complex geometries. Modulus delivers fast, high-resolution surface analysis in places traditional tools can't reach — objective, repeatable data on scratches, corrosion, and edge wear with micron-level accuracy.
- Swappable optics for complex geometries and tight access
- Micron-level accuracy on defects, corrosion, and edge wear
- Objective, repeatable, documented results
