The last application to be explored is incoming material inspection for pharmaceutical and nutraceutical manufacturing, which uses the same fingerprinting ability of Raman spectroscopy as described in the biomedical section above. While this lends itself to a reduction in overall signal efficiency requiring longer integration times, it also means that the spectral range and resolution requirements of the device are often quite relaxed. Over the past 10 years this application has, in part, led to the explosion of handheld Raman systems that can be seen on the market today because of its ability to rapidly speed up material verification process allowing raw materials to pass from the quarantine area to the production floor quickly. In the following we discuss specific application examples of multitrack spectroscopy using free space coupling and fiber coupling of light into the spectrograph. Applications of high-density multitrack spectroscopy. Raman spectroscopy is an ideal tool for the job, since the effect is polarisation sensitive, the orientation of the silicon molecular structure will affect scattered Raman spectra. Raman spectroscopy is widely applied in metamorphic petrology and offers many opportunities for geological and tectonic research. Pure crystalline silicon is far more effective than its amorphous counterpart at converting light into electricity, and because of this, it is used in the production of over 85% of the commercially available solar cells on the market today. Raman is ideal for this application because the laser can be focused through optically transparent packaging allowing for the contents to be analysed without ever opening the product and exposing its contents to the environment. Raman spectroscopy can also detect and quantify strain in micro-inclusions, offering new barometers that can be applied to understand metamorphic and tectonic processes without any assumptions about chemical equilibrium. Although the three applications discussed above are far from the only Raman spectroscopy applications in which Avantes’ miniature spectrometers are integrated, they should serve to provide a framework that a systems integrator can use when deciding which spectrometer would be best for their particular application.
