The invention concerns a bidirectional reflectance distribution meter having a light source which illuminates a sample using pre-determinable elevation and a light receiver, which can be moved relative to the light source in order to receive light from the sample. To this end, it has been designed that the light receiver comprises several receiver elements to collect simultaneously a broad elevation angle range, and that at least one of the light receiver element and the light source is movable around an axis that extends generally vertical to the sample.
