Diffraction grating for colour separation and method for producing the same |
| abstract |
Disclosed is a diffraction grating for color separation comprising a transparent plate with its thickness being varied in repeated step shape along one direction on its plate surface, having a film of plural layers comprising different materials from each other formed on a substrate and having a part of these plural layers subjected successively to etching to form a step shape. Disclosed is also a method for producing the same. |
