Ultraviolet light shielding characteristics display apparatus and the ultraviolet light shielding properties display kit comprising the device

摘要

The present invention sample for a plurality of wavelengths to provide a display device suitable to displaying the resulting visible whether has good ultraviolet light-shielding property. A display device 100 includes a sample holder, a first light source 121, a second light source 122 includes a irradiated portion, a housing 140, a. Sample holder has a light transmissive portion. The first light source 121 emits a first ultraviolet light emission intensity at the first wavelength is maximum, the first ultraviolet light are arranged so as to transmit light transmitting portion. The second light source 122 emits a second ultraviolet light emitting intensity becomes maximum at longer second wavelength than the first wavelength, the second ultraviolet light is arranged so as to transmit light transmitting portion. The irradiated portion is ultraviolet sensor or an ultraviolet visible member holder, it is irradiated by the first ultraviolet light and second ultraviolet light transmitted through the light transmitting portion.FIELD 1
