Glunz1 1Fraunhofer Institute for Solar Energy Systems ISE, 2InfraTec GmbH, 3Rehm Thermal Systems GmbH This protocol describes how to install an infrared camera into a conveyor belt furnace, conduct a customer correction of a factory calibrated IR camera, and evaluate the spatial surface temperature distribution of an object of interest. The example objects are industrial silicon solar cells.
