EdgeScanEdgeScan™ auto edge detection is an internally mounted unit that automatically locates shadow edges.

  • Mounted internally in the main mirror assembly – made by CCP
  • Since it is internal, it does not obscure the viewing screen
  • Ensures accurate, repeatable edge measurements from every user
  • Repeatability better than 0.00008" (2 µm) on optimal edges
  • System does not require frequent calibration like externally mounted units do. Since it is hard mounted internally, the system retains calibration over long periods of time
  • CCP systems equipped with TruLight® LED illumination prolong calibration even further since there is no light level degradation causing a need for re-calibration
  • System truly scans for edges. EdgeScan can be told to seek a single edge, or to automatically scan for the perimeter of an ID or OD hole.
