Technical Examples

In a diffraction optical element in which a plurality of diffraction gratings are laminated and the maximum difference of length among optical paths of light passing through the plurality of diffraction gratins is integer multiples of a plurality of wavelengths, diffraction efficiency is further improved and even when an environmental condition changes, a deviation of the diffraction efficiency is reduced. More specifically, a diffraction optical element is disclosed which includes, as the plurality of diffraction gratings, a first diffraction grating made of a resin material, in which inorganic fine particles are dispersed, and a second diffraction grating made of a material whose organic matter composition is substantially same as that of the resin material.
