摘要： If an optical lens base having a diffraction grating on the surface is made of a resin, a corrosion reaction is produced between the optical lens base and a nanocomposite film material, thus deteriorating performance as a diffractive optical element. In the manufacturing process of a diffractive optical element according to the present invention, the nanocomposite film material is dripped onto a die and then heated and dried, thereby vaporizing away a solvent from the nanocomposite film material. After that, the dies are assembled to form a nanocomposite film with a predetermined thickness on the optical lens base. As a result, a diffractive optical element with excellent optical properties can be obtained without producing a reaction between the optical lens base and the nanocomposite film material.

摘要： A second region (12) composed of a plane is formed around a first region (11) having a lens function, and a third region (13) is formed between the first region and the second region. A protection film (24) is formed on the surface of the first region 1. The first region is protruded relative to the second region, the third region is formed throughout the rim of the first region 1, and the surface of the third region is recessed relative to a virtual curved surface (11a) that is a curved surface along the surface shape of the first region being extended to the second region. Consequently, it is possible to form throughout the first region a protection film having a surface shape that substantially matches the surface shape of the first region.
