1. A hyperspectral element comprising:
a multi filter comprising:
a first sub filter through which first wavelength light having a first wavelength passes; and
a second sub filter through which second wavelength light having a second wavelength passes, the second wavelength being different from the first wavelength; and
a multi detector configured to detect the first wavelength light and the second wavelength light,
wherein the first sub filter and the second sub filter are arranged in series in an optical path of incident light which is incident onto the multi filter,
each of the first sub filter and the second sub filter comprises first refractive index films and second refractive index films that are alternately stacked, and
the first refractive index films have different refractive indexes than the second refractive index films.
