Abstract

Evaluation and testing of Diode Emitters' output became an important part of their manufacturing. When usual methods of photometry and radiometry are applied to DEs, comparison of results obtained at different locations show a great deal of discrepancy. Theoretical considerations will point out the basic problems in measurement of DE type of lightsources compared to the more conventional types. We will show examples where modification of measurement techniques and equipment developed originally for large area lightsources can result in meaningful and reproducible data in case of DEs.
