Beschreibung
Zusammenfassung:	Aspects relate to an integrated and compact attenuated total internal reflection (ATR) spectral sensing device (200). The spectral sensing device (200) includes a substrate (202), a spectrometer (204), and a detector (206). The substrate (202) includes an ATR element (214), a microfluidic channel (208), and a channel interface at a boundary (216) between the ATR element (214) and the microfluidic channel (208) formed therein. The ATR element (214) is configured to receive input light (220) and to direct the input light (220) to the channel interface for total internal reflection of the input light (220) at the channel interface. An evanescent wave produced by a sample contained within the microfluidic channel based on the total internal reflection of the input light (220) attenuates the light output from the ATR element (214) and the resulting output light (222) may be analyzed using the spectrometer (204) and the detector (206).
