This preferential direction is, for each cell, oriented approximately radially with respect to a single point of the spectral filter. Alternatively, this preferential direction is, for each cell, oriented approximately ortho-radially with respect to the single point of the spectral filter. The single point may be a center point. Alternatively, the single point may correspond to an optical axis of a lens element associated with the spectral filter."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Forming of a nanostructured spectral filter","description":"A spectral filter includes an assembly of filtering cells.
