Eliminate the side effects of lighting
FZ3's high dynamic range minimizes the effects of lighting such as halation and allows highly precise
inspections.

The reflective surfaces of cylindrically-curved
workpieces in which conventional vision
sensors have had difficulty can be reproduced.
The surfaces of metal workpieces can be
reproduced accurately.

Any spot outside the dynamic range is blurred by halation
or shadow.
Defects Detectable Even on Reflective or Shadowy Surfaces
Defects Undetectable Due to Overexposure or Underexposure
The surface of the workpiece is accurately reproduced and
detected even with overexposure or underexposure.
