We made a sample with different surface roughness made of inflicting aluminum surface using sand paper abrasive and the centerline average roughness (Ra) was measured. The regular spectrum reflectivity from ultra-violet to infrared area (240〜15,000nm) was measured by spectrum photometer special UV-365 and IR-408, while total reflectivity from ultraviolet to near-infrared areas (340〜1,800nm) was measured by the integration sphere. The results were used to calculate the diffuse reflectivity. Their spectrum characteristics were also examined. Additionally the regular, total and diffuse reflectivity of visible, short wave-length radiation (sun-light), long wave-length radiation and emissivity were calculated by means of their measurements and were comparatively studied to characterize the influence of different roughness.
