1. Apparatus comprising:

  • a fluidic structure with a channel defined therein within which objects travel, the objects being capable of emanating photons as the objects travel within the channel; and

    along the channel, a series of two or more sensing components that obtain information about objects traveling within respective portions of the channel;

    the series including a first sensing component that includes a respective set of cells of a photosensor array, the set of cells photosensing photons within a first range of photon energies that emanate from objects traveling within the respective portion of the channel, the set including a subset of two or more cells each of which photosenses photons in a respective subrange of the first range of photon energies, the subranges of at least two cells in the subset being different from each other.
