PURPOSE: A system for measuring a spectral reflectance of a rock sample is provided to perform a measurement by controlling an incident angle of an artificial light source under a circumstance similar to an imaging photographing time zone. CONSTITUTION: A system for measuring a spectral reflectance of a rock sample comprises a spectral measuring part(1), a holder part(2), an light source part(3), and a controller(4). The spectral measuring part measure a spectral reflectance of a rock sample by using information input by a spectral sensor and the spectral sensor. The holder part is composed of a holder(21) and controlling member(22). The controlling member arranged in the lower part of the holder adjusts a distance between the rock sample and the spectral sensor. The holder part fixes the rock sample to be positioned on the center of the spectral sensor and maintains the balanced state of the rock sample. The light source part comprises a lamp(31), an incident angle controlling unit(32), an arm unit(33), and a stand(34). The controller is composed of a PC(41) and automatic voltage controller(42).
