Figure 6: Spectra of a wIRA radiator and of protoporphyrin IX (PPIX)
wIRA radiator: Calculated for Hydrosun® 501 with 4 mm water cuvette and orange filter OG590 at 250 mW/cm² (= 2.5 x 10³ W/m²) total irradiance (approximately 190 mW/cm² water-filtered infrared-A (wIRA) and 60 mW/cm² visible light (VIS)), from Measurement of University of Applied Sciences Munich, dated 30th June 1999 (from [26])
PPIX: Qualitative presentation (e.g. only relative scaling of ordinate scale) for comparison of absorption diameter of protoporphyrin IX (PPIX) monomeres in DMSO. (from [26], adapted from [55])
