Abstract
The present application describes a NIR spectrometer for label-free, rapid, portable and high-precision molecular composition analysis of a sample. The NIR spectrometer is integrated in a lab-on-chip and comprises a broadband NIR source configured to generate NIR light pulses; collimating and focusing objectives; a PDMS chamber mounted on a silicate glass support and designed to be filled with the sample and to receive an NIR light beam from a channel waveguide; the cannel waveguide built in a silicate glass support and configured to transmit the NIR light beam through the sample; an optical spectrum analyser configured to receive the NIR light beam, partially absorbed by the sample, and to measure an output signal intensity of the light beam versus a wavelength of said light beam; optical fibres connecting the components of the NIR spectrometer; and a computing unit.
