Abstract
A spectroscopic measurement system, which may utilize multiple plasmonic filters associated with a cuvette to monitor different wavelengths of light. The spectroscopic measurement system may measure absorbance and or fluorescence, and may have built-in low cost CMOS image sensor(s). Reagents and samples may be introduced to the cuvette from a fluidics manifold. Multiple sets of combined cuvettes, image sensors and plasmonic filters may utilize a single fluidics manifold for reagent and sample distribution.

A spectrometer system comprising:
- a light source and a two dimensional sensor,
- a collimating element configured to collimate said light from said light source to provide collimated light,
- a cuvette having a first and second at least partially mirrored surfaces arranged to contain a fluid sample, wherein said collimated light from said light source is directed through said cuvette, and
- a plasmonic filter positioned after said collimating element and before said two dimensional sensor, wherein said plasmonic filter comprises dielectric and metallic regions configured to differentially transmit selected wavelengths of said collimated light received from said collimating element to said two dimensional detector.
