摘要： A diffractive optical element 1 comprises a first element 10 and a second element 20, whose materials are different from each other. These elements are bonded to each other, with a diffraction grating 30 created on the boundary surface between the first element 10 and the second element 20, and in the diffractive optical element 1, at least the second element 20 is made from a photo-setting resin, which is set by light rays incident through the first element 10. The diffractive optical element 1 is set in a predetermined range of values including values that make the transmittance T1 of the first element 10 and the transmittance T2 of the second element 20 equal to each other for the light rays. As a result, as differences in cure shrinkage in the second element 20 are generated by differences in the intensity of the light rays caused from ups and downs of the diffraction grating 30 created on the surface of the first element 10, the differences in cure shrinkage are controlled within a range so as not to degrade the desired performance of the diffractive optical element 1.
摘要翻译：衍射光学元件1包括其材料彼此不同的第一元件10和第二元件20。这些元件彼此结合，在第一元件10和第二元件20之间的边界表面上形成衍射光栅30，并且在衍射光学元件1中，至少第二元件20由光固化树脂，其由通过第一元件10入射的光线设定。衍射光学元件1被设定在包括使第一元件10的透射率T 1和第二元件20的透射率T 2相对于光线的值的值的预定范围内。结果，由于第二元件20中的固化收缩率的差异是由在第一元件10的表面上产生的衍射光栅30的上下颠簸引起的光线强度的差异产生的，所以固化收缩率的差异被控制在不会降低衍射光学元件1的期望性能的范围内。
