noun, Optics. 1. . [muh-loos; French ma-lys] /məˈlus; French maˈlüs/ noun, Optics. 1. the law stating that the intensity of a beam of plane-polarized light after passing through a rotatable polarizer varies as the square of the cosine of the angle through which the polarizer is rotated from the position that gives maximum intensity.
