    A method and device for fatigue testing of photochromic, fluorescent or phosphorescent dyes

  • Original language description

    The invention relates to a method for fatigue testing of photochromic, fluorescent or phosphorescent dye/dyes or of a mixture of at least two of them, in which a sample (3) containing photochromic, fluorescent or phosphorescent dye/dyes or a mixture of at least two of them is exposed to a predetermined number of cycles of luminous exposure to an excitation light beam (81), which evokes a color response of the photochromic, fluorescent or phosphorescent dye/dyes or of the mixture of at least two of them in the sample (3). Before and/or during and/or after each predetermined exposure to the excitation light beam (81), the sample (3) containing the photochromic, fluorescent or phosphorescent dye/dyes or of the mixture of at least two of them is exposed at least once to irradiation by an exposure light beam (71), due to which the dye/dyes is/are subject to fatigue loading. Simultaneously, a measuring light beam (41) is introduced to the sample (3) and is reflected from it, whereby the change and/or the course of the change in the characteristics of the measuring light beam (41) reflected from the sample is monitored by a spectrometer (94). From this change and/or the course of the change it is possible to deduce the course of the color response and/or the change in the color response of the particular photochromic, fluorescent or phosphorescent dye/dyes or of the mixture of at least two of them in the sample (3) to the exposure to an excitation light beam (81) and thus it is possible to deduce the fatigue of this photochromic, fluorescent or phosphorescent dye/dyes or of the mixture of at least two of them. The invention also relates to a device for carrying out this method. RIV18 - No licence.
