1. An imager comprising:

  • a filter formed to transmit light within a predetermined wavelength range; and

    a pixel matrix configured to receive the light through the filter, the pixel matrix comprising an N×

    M array of selectable photosensitive elements, wherein the N×

    M array comprises a pinned photodiode structure formed in a region of photosensitive semiconductor material, and an n-type conductive region positioned between a charge carrier sink and the pinned photodiode structure, and wherein a volume between the n-type conductive region and the pinned photodiode structure is configured to prevent charge carriers from entering the photosensitive semiconductor material during an integration time.
