:  Optimization of a light emitting diode (LED)‐based excitation system for the detection of pretreated fingerprint fluorescence is described. Fluorescent ridges can usually be excited by irradiation with forensic light sources such as xenon arc lamps or quartz‐halogen lamps with high‐power output a...
