We are trying to take Near infrared (600-1100nm) spectrum of milk. We failed to transmit any light through even a thin layer (0.5mm) of milk. Hence, we are considering to design transflectance (transmission+diffused reflection) unit for our home-made spectrometer.
How can we setup optical fiber unit to pick up light from the source and deliver it to the slit of the spectrometer?
Thanks.
