Abstract: An optical multilayer thin-film system (11) includes a number of high refractive index layers (13), and a number of low refractive index layers (14) alternately laminated with the high refractive index layers. Each high refractive index layer has an optical thickness larger than that of each low refractive index layer. When such a multilayer thin-film system is applied to an optical element, spectral shift with respect to variation of the incident light angle is significantly reduced.
