i2S LineScan Inc., a supplier of online and offline camera-based visionsystems for optical defect detection and feature metrology, hasintroduced the PV-4000, a thin-film photovoltaic application-specificmachine design.
Utilizing standard software, the inspectionsystem can inspect glass-panel, roll-to-roll metallic or filmsubstrates. Typical inspection cells are located for incominginspection of the substrate, after metallization and after scribing.
Opticaldefects – such as raw glass defects, metal surface defects and filmdefects – are detected in the substrate, and non-uniformity, pinholesand contamination are detected in the metallization layers. Scribe linespacing and edge deletion features can be trended.
Dependingupon throughput requirements, resolution can be as fine as 5 micronsusing 8192 pixel linear array cameras and proprietary illumination. Afree sample evaluation is provided upon request, the company adds.
