ABSTRACT:
A diffractive optical system including a diffractive optical element has a concave lens component having a first diffractive optical surface, and an optical member having a second diffractive optical surface, the concave lens component and the optical member being arranged so that the first diffractive optical surface and the second diffractive optical surface face each other, and the conditional expression 0.003<t/f<0.3 being satisfied, where t is the thickness of the concave lens component on the optical axis, and f is the focal length of the diffractive optical system.
