OPV is one of the most promising future technologies in the PV industry.[more]
In-Line Scanner for Prerecorded Optical Media: CD, DVD-5, DVD-9, DVD-10, DVD-14, DVD-18
Trend-Setting Technology for In-Line Inspection and Measurement
Reliable quality assurance and process control for prerecorded CDs and DVDs requires the integration of Final Scanners into replication lines. The ISM.cd and ISM.dvd detect local defects at high speed, measure disc deformation with high precision, and, for the first time in industry, measure space layer and substrate thickness simultaneously, according to DVD-9 specifications. Additional features include detection of Focus Error, and Electrical Signal Testing, areas in which Dr. Schenk sets new trends in technology to ensure quality and support process optimization.
High Speed Inspection Technology
- Reliable detection of local defects including bonding gaps in reflection mode on final discs
- Double sided disc inspection of top and bottom half disc, e.g. for DVD-9, DVD-10, DVD-14, DVD-18
- Reliable detection of local defects on lacquering for CD
High Precision Measurement Technology
- Radial and tangential disc deformation measurement → 1000 measurement points per disc
- Simultaneous space layer and substrate thickness measurement → in-line with DVD-9 specification
Optional Inspection and Measurement Channels
- Enhanced bonding gap detection with additional inspection channel for DVD-5, DVD-10
- Enhanced acceleration defect detection with additional inspection channel
- Reflectivity measurement over the entire disc
- Detection of resin overflow and shortage
- Crack sensor to detect cracks in the center hole area
- Barcode reader (single or double sided)
- Focus error - detection of abrupt local variations in space layer thickness
- ETI - the in-line DVD pick up head sensor for electrical signal testing in-line
- NetSis - Networking Schenk Inspection System
