FLATNESS OR CURVATURE OR BOW MEASUREMENT

Radius of Curvature Measurement

The distance from the center of a circle or sphere to its surface is its radius. For other curved lines or surfaces, the radius of curvature at a given point is the radius of a circle that mathematically best fits the curve at that point.

Rtec instruments has various options to characterize radius of curvature from nm to several mm level.

White light interferometer
  • Scanning white light mode for depth more than 150nm
  • Phase shift mode with green, blue or red light for depth under 150nm
  • Sub nm Z resolution from white light interferometer
  • 100x to 2,5x magnificationn
  • Scan large or small samples (XY stage 210x200mm)
  • Also creates 3d image
