Product Introduction:
       The fully automatic PV-LIT testing system offers individual and serial testing options for solar cells and complete solar modules. The modular testing system allows easy integration into existing production lines and can be used in automated serial testing for quality assurance.
       PV-LIT inline guarantees 100 % quality inspection during the manufacturing process. Cycle times of less than 1 second and a continuous operation allows reliable tests in serial production.
 
Product Feature:
■ Use of either cooled or uncooled camera systems depending
■ On problem definition and customer requirements
■ Testing possible at very early stage of production
■ Cycle times of less than 1 second
■ Inspection for different defect types Various testing options
■ For different kinds of defects
■ Definition of user-defined test parameters (threshold,
■ Temerature level, number and size of defects)
■ Fully automated testing with classification
■ Flexible data interfaces (e.g. Ethernet, Profibus)
■ Long-term stability and continuous duty capability
