A measurement system includes a light source having semiconductor sources configured to generate an input optical beam, a multiplexer configured form an intermediate optical beam from the input optical beam, fibers including a fused silica fiber configured to receive the intermediate optical beam and to form an output optical beam. The output optical beam comprises wavelengths between 700 and 2500 nanometers with a bandwidth of at least 10 nanometers. A measurement apparatus is configured to deliver the output beam to a sample to generate a spectroscopy output beam. A receiver is configured to receive and process the spectroscopy output beam to generate an output signal, wherein the receiver processing includes chemometrics or multivariate analysis methods to permit identification of materials within the sample, the light source and the receiver are remote from the sample, and the sample includes plastics or food industry goods.
