Claim Text:
1. An article comprising: first and second parts; each of the first and second parts including a respective container and being configured to form an optical device comprising a first light reflective component having a first reflective surface that is at least partially reflective and a second light reflective component having a second reflective surface that is at least partially reflective arranged to face the first reflective surface, the optical device having a light-transmissive region that is at least partially bounded by the first and second reflective surfaces of the light-reflective components, the light-reflective components and the light-transmissive region configured to reflect light more than once across the light-transmissive region, the first light reflective component configured to allow input light to enter the light-transmissive region through the first light reflective surface; and one or both of the first light reflective component and the second light reflective component configured to allow output light to exit the light-transmissive region through the one or both of the first light reflective surface and the second light reflective surface, the optical device having a respective optical spectrum characteristic that can be affected by presence of spectrum-affecting objects in the container; the optical spectrum characteristic providing the output light in response to the input light in a set of optical modes providing higher intensity light in some photon energy subranges relative to light in other photon energy subranges, the modes spaced apart as a function of photon energy, the respective container having a respective set of one or more bounding regions through which objects in fluid can transfer between the container's interior and exterior; and first and second fluidic components that control transfer of objects in fluid through the respective bounding regions of the first and second parts, respectively; the first fluidic component permitting transfer of a first set of the spectrum-affecting objects into the light transmissive region of first container at a more rapid rate than spectrum-affecting objects not in the first set; the second fluidic component permitting transfer of a second set of the spectrum-affecting objects into the light transmissive region of the second container at a more rapid rate than spectrum-affecting objects not in the second set; the first and second sets of spectrum-affecting objects both including a shared subset; the first set including a non-shared subset that the second set does not include; objects that are instances of an analyte type being predominantly in the non-shared subset.
