| titleOfInvention | Laminated diffractive optical element |
| abstract | A laminated diffractive optical element including a colorant-containing first layer having a diffraction grating surface with a grating height X and a second layer closely stacked on the diffraction grating surface of the first layer, wherein the relation of internal transmittances T λ, a and T λ, b of a material (a) for forming the first layer and a material (b) for forming the second layer satisfies the following (Formula 1) and the relation of the maximum and minimum internal transmittances T λ, MAX and T λ, MIN of the laminated diffractive optical element satisfies the following Formula (2):n n2.0%≦| T λ,a −T λ,b | (Formula 1)n n T λ,MAX −T λ,MIN ≦8.0% (Formula 2)n nThis reduces shading on the image surface resulting from the difference in transmittance of the optical element to provide a laminated diffractive optical element having reduced variation in transmittance. |
