A light applying device, for example as shown in Figure 1, comprises an optical filtering member (35) for emitting rays of light emitted from the light source (30) which are in a predetermined range of wavelengths. and a heat eliminating member (48) for eliminating a heat emitting from the optical filtering member (35), wherein the heat eliminating member (48) is located between the optical filtering member (35) and the subject. A liquid-cooling unit (45) may be provided as the heat eliminating member (48), including a transparent liquid filled in a space defined by two transparent portions. <IMAGE> |
