  • OPTICAL FILTER STRUCTURE FOR ARBITRARY COMBINATION OF RGB AND IR WAVELENGTH RANGES AND ITS MANUFACTURING METHOD
    Publication number: 20230335652
    Abstract: The present invention discloses an optical bandpass filter structure targeting an arbitrary combination of the spectral ranges of R (red), G (green), B (blue) and IR (infrared) light, which comprises a substrate that is a wafer-based semiconductor sensing element, and a filter layer that is formed on one side of the substrate. The filter layer includes a plurality of basic units organized as a two-dimensional array, in which each of the basic units is composed of a plurality of pixel filter films fabricated by a vacuum coating method.
