| Zusammenfassung: | A reflective measuring scale graduation, as well as a method for manufacturing the same are described. The reflective measuring scale graduation includes first and second subdivisions having different reflection properties, which extend in at least one first direction on a reflecting substrate. The highly reflecting first subdivisions are made of a plurality of partial layers having different indices of refraction and function as an interference filter. The low reflecting second subdivisions are composed of at least one absorber layer on the substrate. |
