Projectron™ auto edge detection is an internally mounted unit that automatically locates edges using gray-scale processing.

• Mounted internally in the main mirror assembly – made by OGP

• 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

• OGP systems equipped with TruLight® LED illumination prolong calibration even further since there is no light level degradation causing a need for re-calibration

• Projectron truly scans for edges. Using the functions of the Q-Check controller, Projectron can be told to seek a single edge, or to automatically scan for the perimeter of an ID or OD hole.
