LSA automation and greateyes offer an advanced LumiSolarProfessional (LSP) inline inspection system for pre-laminates and solar modules. The tool is not only capable to detect micro cracks, low intensity cells and contaminations, it also determines misaligned bus bars, rotated solar cells and other quality issues fastly.

The LSP Inline system exhibits a fast cycle time below 30sec including feed-in, inspection, automatic defect recognition, pass/fail decision and unloading. The unique design of the tool provide significant higher throughput and analysis power compared to conventional in-line EL inspection tools. Precise quality control, higher yield and cost savings are the main reason for implementing the machine in the production line. In contrast to other vendors the new inspection system uses two scientific greateyes cameras in combination with high-throughput objectives allowing for fast detection of the weak electroluminescence. Furthermore an innovative automatic image analysis software provides superior performance in the detection of failures within pre-laminates or solar modules.

  • Turn-key Inline EL Inspection System
  • Excellent image quality
  • Fast cycle time
  • automatic defect identification and classification
  • detection of misaligned cells and bus bars
