Abstract

Several types of non-coherent light sources can be used for dermatological applications of photodynamic therapy (PDT). Such sources are relatively inexpensive, stable, and easy to operate, requiring very little maintenance. A further advantage is that large lesions can be irradiated in a single treatment. In order to assess the matching of the spectral output of the light source with the photochemo-therapeutic agent chromophore, a measurement of spectral irradiance with a monochromator must first be carried out. Also, in order to assure flatness of irradiation field over the entire bandwidth, an irradiance measurement as a function of position in the beam must be performed. Data of this type obtained from different light sources is presented and discussed in terms of predicted PDT efficacy.
