Patent

CA 2649772

The invention relates to a spectral filter (100) comprising at least one metal layer (101) structured by a grating of traversing slots (102a to 102e, 103a to 103h). The grating consists of at least two subgratings of traversing slots (102a to 102e, 103a to 103h) intercepting one another perpendicularly.

L'invention concerne un filtre spectral (100) comportant au moins une couche métallique (101) structurée par un réseau de fentes traversantes (102a à 102e, 103a à 103h). Le réseau est constitué d'au moins deux sous réseaux de fentes traversantes (102a à 102e, 103a à 103h) se coupant perpendiculairement les unes aux autres.
