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.

Claim (Index 1):
A near-infrared (NIR) spectrometer for label-free molecular analysis of a sample, said NIR spectrometer is integrated in a lab-on-chip and comprises:\n a) a broadband NIR source configured to generate NIR light pulses; b) a single-mode (SM) optical fibre optically connecting the broadband NIR source with a collimating objective and designed to transmit said NIR light pulses from said NIR source to said collimating objective; c) the collimating objective configured to collimate the NIR light pulses received from the NIR source into a narrow collimated NIR light beam, and directing said narrow collimated NIR light beam to a focusing objective; d) the focusing objective configured to receive the narrow collimated NIR light beam from the collimating objective, to align on-axis the NIR beam and to focus said beam onto a polarisation maintaining optical fibre; e) the polarisation maintaining (PM) optical fibre optically coupled into a channel waveguide of a polydimethylsiloxane (PDMS) chamber, optically connecting the focusing objective with the channel waveguide, and configured to transmit the focused NIR light beam from the focusing objective into the channel waveguide; f) the PDMS chamber mounted on the silicate glass support and designed to be filled with the sample and to receive the NIR light beam from the channel waveguide; g) the cannel waveguide of the PDMS chamber, built in a silicate glass support and configured to transmit the NIR light beam to and from the PDMS chamber; h) a multi-mode (MM) optical fibre optically coupled into the channel waveguide of the PDMS chamber, optically connecting the channel waveguide with an optical spectrum analyser and configured to transmit the NIR light beam into the optical spectrum analyser; i) the optical spectrum analyser configured to receive the NIR light beam, partially absorbed by the sample and transmitted from the PDMS chamber, to measure an output signal intensity of the NIR light beam versus a wavelength of said NIR light beam, and to transfer the obtained signal intensity data to a computing unit; and j) the computing unit configured to receive the signal intensity data from the optical spectrum analyser, to perform calculations relating to mathematical analysis of the data and to display said data in a readable format or to plot said data in a form of a transmittance or absorbance spectrum of the sample.
