The LumiSolarProfessional Series allows flexible electroluminescence (EL) Characterisation of Solar modules and Strings of many different types and sizes. Scientific, low noise cameras with high-performance objectives are employed for electroluminescence measurements, resulting in an excellent image quality with true 16bit dynamic range. Therefore all defects are imaged with high contrast and in great detail, even weak inhomogenities can be precisely identified. The various models of the LumiSolarProfessional Series differ with respect to measurement design and resolution, matching each individual application in the optimal way. The software can be equipped optionally with an automatic image analysis and defect identification module. Typical application areas for the LumiSolarProfessional Series include off-line inspection in production, piecewise receiving and outgoing inspection, quality assurance as well as sophisticated research and development.

Data Sheets


LumiSolarProfessional Software

The LumiSolarProfessional software controls the camera, the linear drive table and visualizes the data sets. The program can generate intensity profiles from the 16bit high dynamic range image data. Basic picture manipulation procedures are included in the software. Dimension measurements of artefacts are possible following calibration as well as remote control of power supply. Automatic Analysis of electroluminescence images is available as an option.
