High speed disc inspection
- Matrix camera with custom-made high resolution optics for a resolution of 60 µm
- LED illumination at the optimum wavelength for the sample and task
- Camera inspection within the split of a second
- Simultaneous defect detection and barcode verification
Each disc is usually tested by an inline scanner after the replication process, before printing. But the print process may cause ink splashes and the handling procedure may cause scratches or other defects at the disc's read-out side. In order to detect those defects, dr. schwab offers an after-print inspection solution: the FPI disc MA, based on a 4 megapixel matrix camera.
The main field of application of the system lies in read side inspection of optical discs after the printing process. A high resolution matrix camera offers full surface defect detection with a resolution of 60 µm, even on the inner area of the disc. Combined with dr. schwab's advanced defect classification and trend analysis features the system provides reliable information for quality and process control.
