ABSTRACT:
A diffractive optical system including a diffractive optical element is provided with a first lens component having a first positive lens, and a second lens component having a second positive lens and a negative lens. The diffractive optical element has a first diffractive optical member having a first diffractive optical surface, and a second diffractive optical member having a second diffractive optical surface. The first diffractive optical member and the second diffractive optical member are arranged so that the first diffractive optical surface and the second diffractive optical surface are in contact with each other. A refractive index of the first diffractive optical member and a refractive index of the second diffractive optical member at the d line are different from each other.
