摘要： A test device includes a thermostatic tank, a heater, a rotary sample stage, a black panel thermometer, a light source, an in-tank thermometer, a sprayer, and a controller. The sprayer sprays water to samples placed on sample placement units of the rotary sample stage and the black panel thermometer. Mist droplets of mist sprayed by the sprayer are set in a range in which a decrease in temperature of the samples and the black panel thermometer irradiated with light is suppressed by spraying to the samples and the black panel thermometer.

摘要： The inventive system for analyzing electromagnetic radiation comprises: an enclosure filled with gas containing atoms of a known type, at least one light source emitting light capable of exciting the atoms of the known type in the gas, a source of the electromagnetic radiation to be analyzed arranged such that the emitted electromagnetic radiation acts on the atoms of the known type in the gas, and a sensor for capturing light emitted by and/or passed through the gas. Further, the system comprises an electrical field source and/or magnetic field source configured to establish a predefined electrical field and/or magnetic field acting on the atoms of the known type in the gas. The light captured by the sensor reflects a response of the atoms of the known type in the gas on the electrical field and/or the magnetic fields, the light from the at least one light source, and the electromagnetic radiation to be analyzed.

摘要： A method of determining degradation of a thermoplastic when exposed to light and heat includes illuminating the thermoplastic with a desired wavelength of light at a desired irradiance while maintaining the ambient air surrounding the thermoplastic at a desired temperature. The method is useful to measure the discoloration rate of transparent, translucent and opaque thermoplastics such as polycarbonates, the discoloration rate being determined by transmission or reflectance spectra of transmitted or reflected white light through or from the thermoplastic.

摘要： A method and a device 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.

摘要： An evaluation method for evaluating the ultraviolet protection effect of a measurement sample applied on a substrate includes measuring, at predetermined wavelength intervals, a change over time of a spectral transmission spectrum of the measurement sample within a predetermined wavelength range by irradiating light from a light source that includes ultraviolet light, visible light, and infrared light under a predetermined irradiation condition; establishing, based on the change over time of the spectral transmission spectrum, a correlation between a light irradiation time and an erythema effective dose per unit time, which is obtained by dividing an erythema effective dose of the measurement sample by an erythema effective dose per 1 MED; and calculating an in vitro rSPF predictive value for the measurement sample on the basis of a time until a cumulative erythema effective dose, which is obtained through time integration based on the correlation, reaches 1 MED.
