A spatial light modulator includes a prism group and satisfies either of the following conditions <?in-line-formulae description="In-line Formulae" end="lead"?>d<0.95xlambda/(2x(n-1)),<?in-line-formulae description="In-line Formulae" end="tail"?> <?in-line-formulae description="In-line Formulae" end="lead"?>d>1.05xlambda/(2x(n-1))<?in-line-formulae description="In-line Formulae" end="tail"?> where d is a distance between a reference surface and a flat surface, lambda is a wavelength of an incident light, and n is a refractive index of the prism group.
