SIMULATED SOLAR LIGHT APPLICATION DEVICE

摘要

Xenon light applied from a xenon light source (1) travels to a wavelength selection mirror (7) through a taper coupler (5) and an air mass filter (5a). The wavelength selection mirror (7) reflects the short-wavelength side of the xenon light and emits the reflected short-wavelength side to a taper member (8). Halogen light applied from a halogen light source (2) travels to the wavelength selection mirror (7) through a taper coupler (6) and a reflecting mirror (10). The wavelength selection mirror (7) transmits the long-wavelength side of the halogen light therethrough and emits the transmitted long-wavelength side to the taper member (8). The width of the taper member (8) gradually reduces from the light incidence surface thereof toward the light emission surface thereof. Light emitted from the taper member (8) changes such that the radiation directivity of components originating in the xenon light and the radiation directivity of components originating in the halogen light are similar to each other. Thus, a simulated solar light application device (30) which applies simulated solar light having a uniform application distribution to an application surface (12) is provided.
