ABSTRACT:
A miniaturized fluidic spectrometer comprises a light source, a fluidic circuit having a plurality of flow channels through which an analyte flows, and a proximity detector array for detecting light from the light source transmitted through the fluidic circuit. Where the light source is broadband, a variable filter is disposed between the detector array and the fluidic circuit so that each position of the detector array is provided with a different wavelength response. The fluidic circuit is disposed in an optimized Fabry-Perot etalon. The fluidic circuit is defined in an elastomeric material and includes means for tuning the Fabry-Perot etalon by pressurization of flow channels in the elastomeric material.
