Paper Brightness Tester

Definition : Brightness is a commonly used industry term for the numerical value of the reflectance factor

of a sample with respect to blue light of specific spectral and geometric characteristics. This method requires an

instrument employing 45° illumination and 0° viewing geometry with the illuminating and viewing beams adjusted so that translucent materials are evaluated on an arbitrary but specific scale . the directional reflectance is measured at 457 nm.
