| titleOfInvention | Diffractive optical element and method of manufacturing the same |
| abstract | An object of the present invention is to prevent deterioration of optical performance due to water absorption of a resin layer in a diffractive optical element, and the occurrence of cracking at a high temperature or low temperature and peeling at an interface of the resin layer. A diffractive optical element including a first layer and a second layer sequentially stacked on a substrate, and an interface between the first layer and the second layer forms a diffraction grating, The height d of the grating portion of the diffraction grating, the average film thickness t1 of the first layer, and the average film thickness t2 of the second layer are 1.1 × d ≦ t1 ≦ 50 μm 30 μm ≦ t2 ≦ (400 μm-t1-d) A diffractive optical element characterized by satisfying the following relationship: [Selected figure] Figure 1 |
