Abstract: A reflective coating belongs to a reflection structure for reflecting a light beam emitted by a light source of an optical encoder, the reflection of the light beam being directed toward a photoreceptor. The reflective coating includes at least one flat lamella made of glass, a first face of which forms a connection surface on one portion of the reflection structure of the optical encoder. A second face of the lamella opposite the first face forms another connection surface to connect with at least one layer made of at least one material having a reflection coefficient greater than 96% coated with a protective layer.

Abstract: The invention relates to a reflective coating (12) for means for reflecting a light beam emitted by a light source of an optical encoder, the reflection of the light beam being directed toward a photoreceptor. The coating (12) comprises at least one flat lamella made of glass, one face of which forms a connection means on one portion of the reflection means of the optical encoder, the lamella being provided, on the face opposite the face forming the connection means, with at least one layer made of at least one material having a reflection coefficient greater than 96% coated with a protective layer.
