What It Detects
Gels · fisheyes (fish-eyes) · black specks · fibers · wrinkles · holes — classified by type and size in real time, with results in the units your customer contracts in: defects/m², mm²/m², or PPM of defect area.
How It Works
The scanning head mounts directly on your laboratory blown-film or cast-film machine. Film produced by the line passes continuously through the camera inspection zone, where a high-resolution line-scan camera combined with a high-brightness LED line light captures the surface. The software classifies every defect against your thresholds, displays a defect map of the film, and builds statistics in real time — completely unattended.
