Irreproducibility in some reflection measurement methods arises from the observance of the haze component of reflection (non‐regular‐specular, non‐Lambertian). Because of the haze component, the measured reflection is sensitive to the apparatus configuration. We show the effects of detector lens aperture and detector distance on the measurement of the reflected luminance. Only for detectors with small subtense angles can reproducibility be assured when haze reflection is nontrivial.
