摘要： A plurality of darkness distributions having a predetermined relationship with a darkness distribution for ND-filtering transmission light at the position of an aperture blade in an aperture device are formed on an original. The original is photographed on a film by a camera, and after the film is developed, the film is molded to obtain a plurality of ND filters.

摘要： This invention prevents a degradation in image quality resulting from undesirable reflected light and undesirable transmitted light generated near the ridgeline of the edge portion of an optical element including an aperture blade or an ND filter. The aperture edge of the aperture blade cooperates with the aperture edge of another aperture blade to form an almost rhombic aperture. A small saw-toothed and non-periodic uneven portions having various sizes are formed along two, front and rear ridgelines of the aperture edge and along those of the ND filter. When incident light beams strike the aperture edge of the aperture blade or the edge of ND filter, the uneven portions formed at the ridgeline reflect them in various directions.
摘要翻译：本发明防止由于不期望的反射光和包括孔径叶片或ND滤光器的光学元件的边缘部分的棱线附近产生的不期望的透射光所导致的图像质量的劣化。光圈叶片的孔径边缘与另一个光圈叶片的孔径边缘配合以形成几乎菱形的孔。具有各种尺寸的小锯齿状和非周期性的不均匀部分沿着孔边缘的两个前，后脊线和ND滤镜的棱脊形成。当入射光束撞击孔径叶片的孔边缘或ND滤光片的边缘时，形成在棱线处的不平坦部分在各个方向上反射它们。
