Abstract:
A diffractive optical element  10  includes a first diffraction grating  4 , a second diffraction grating  5 , films  6  formed between the first diffraction grating  4  and the second diffraction grating  5 . The DOE  10  satisfies a conditional expression of n 2 <n 1 <n ha , where n ha  is an average refractive index of films  6 b  formed between grating wall surfaces  4 b  and grating wall surfaces  5 b  at a wavelength of 550 nm, n 1  is a refractive index of the first diffraction grating  4  at a wavelength of 550 nm, and n 2  is a refractive index of the second diffraction grating  5  at a wavelength of 550 nm. The films  6 b  and films  6 a  that are formed between grating surfaces  4 a  and grating surfaces  5 a  satisfy a predetermined relationship.

Claim (Index 10):
The diffractive optical element according to  claim 8 , wherein the following conditional expression is satisfied:\n [sin {\u03b1\u00d7 d s ( r )}\u00d7{ n 1 +n 2 \u22122 n s ( r )}] 2 <0.2, and \u03b1=0.016564 nm \u22121 , where d s (r) [nm] is a thickness of a part of the film that is formed between the grating surface of the first diffraction grating and the grating surface of the second diffraction grating at a position a distance r away from a center of the concentric diffraction gratings, and n s (r) is a refractive index at a wavelength of 550 nm of the part of the film that is formed between the grating surface of the first diffraction grating and the grating surface of the second diffraction grating at the position a distance r away from a center of the concentric diffraction gratings.
