NORTHAMPTON, England, May 15, 2013 — Armstrong Optical Ltd. has introduced PV-LIT, a fully automatic optronic IR test system manufactured by InfraTec GmbH in Germany for use in solar cell and solar module testing. The system uses the megapixel resolution of the VarioCam High Definition and ImageIR 9300 cameras to facilitate serial and individual testing of solar cells and complete solar modules. The system enables testing for several types of defects and numerous decisive testing criteria, such as limit values, temperature levels and number/size of defects. Short cycle times of less than a second combined with continuous operation allow the system to operate in serial production environments, and the open control architecture of PV-LIT ensures that data interfacing and integration are optimized to meet the end-user requirements and local conditions. It is possible to operate the system with either uncooled or cooled camera systems. InfraTec’s uncooled VarioCam High Definition camera delivers resolutions of up to 2048 × 1536 (3.1 M) IR pixels, while the cooled ImageIR 9300 delivers up to 1280 × 1024 IR pixels, so that even small failures can be captured.
