Abstract
Official abstract text for this publication.
An evaluation method for evaluating an ultraviolet radiation protection effect in a measurement sample applied on an application member includes the first step of switching to a first filter for measuring a spectral transmittance before photodeterioration by emission of light from a light source, and measuring the spectral transmittance, the second step of switching to a second filter for ultraviolet irradiation and causing the photodeterioration by the emission of the light after the measurement by the first step, and thereafter, switching to the first filter and measuring the spectral transmittance, and the third step of evaluating the ultraviolet radiation protection effect based on a change over time in the spectral transmittance obtained by the second step. Each of the first and second filters includes multiple light source filters. The first filter includes ND filters switchable in accordance with the light amount of the light source in the light source filters.
First claim
Opening claim text (preview).
The invention claimed is: 1. An evaluation method for evaluating an ultraviolet radiation protection effect in a measurement sample applied on an application object member, comprising: a first step of switching to a first filter for measuring a spectral transmittance before photodeterioration in a predetermined wavelength range by emission of light including ultraviolet radiation from a light source according to a preset light emission condition, and measuring the spectral transmi…
