A reflectometer 1 is designed to measure the reflectance of a sample 2 with a variable angle of incidence. To accomplish this, reflector 1 comprises a box or housing 3 in which is mounted a sample holder 4. Sample 2 is designed to be mounted on holder 4, which in turn is mounted for rotation on a shaft or bearing 5 with the axis of rotation passing along the surface of the sample from which the reflectance is being measured. A illuminating fiber-optic bundle 6 is mounted on an arm 7 for rotation with holder 4 and sample 2, the fiber-optic bundle being oriented so that light emerging therefrom along the axis thereof is perpendicular to the surface.
