摘要：
PROBLEM TO BE SOLVED: To suppress occurrence of flare light by applying matting to the vertical surface of a diffraction grating in a diffractive optical element having a blazed diffraction grating whose cross-section is worked into a sawtooth waveform.
SOLUTION: In the molding die for diffractive optical element, only the vertical surface of a blazed diffraction grating part is turned into a minute structure by forming the film of a carbonaceous film composed of two layers having different surface roughness. The matting is carried out to the vertical surface of a diffractive optical element by transferring such a shape to a molded product.

要解决的问题：通过在具有截面被加工成锯齿波形的闪耀衍射光栅的衍射光学元件中的衍射光栅的垂直表面上施加消光来抑制耀斑光的发生。 解决方案：在用于衍射光学元件的模具中，通过形成由具有不同表面粗糙度的两层构成的碳质膜的膜，仅将闪耀的衍射光栅部分的垂直表面转变成微小的结构。 通过将这种形状转印到模制产品上，通过衍射光学元件的垂直表面进行消光。 版权所有（C）2006，JPO＆NCIPI
