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;

Abstract
An implantable product such as an article, device, or system can include analyte and non-analyte containers in parts that can be operated as optical cavities. The product can also include fluidic components such as filter assemblies that control transfer of objects that affect or shift spectrum features or characteristics such as by shifting transmission mode peaks or reflection mode valleys, shifting phase, reducing maxima or contrast, or increasing intermediate intensity width such as full width half maximum (FWHM). Analyte, e.g. glucose molecules, can be predominantly included in a set of objects that transfer more rapidly into the analyte container than other objects, and can have a negligible or zero rate of transfer into the non-analyte container; objects that transfer more rapidly into the non-analyte container can include objects smaller than the analyte or molecules of a set of selected types, including, e.g., sodium chloride. Output light from the containers accordingly includes information about analyte.
