An innovative fabrication method is presented that affords the combination of polydimethyl-
siloxane (PDMS) microfluidic technology with vibrational spectroscopy. PDMS devices are
produced with uniform thicknesses ranging from 25 to 400 μm. The optical characteristics of
the microfluidic devices in the mid-infrared are reported. The broad utility of this approach is
demonstrated through IR imaging of flows in functional gradient generators and flow-
focusing devices.
