Inline Spectroscopy: From Concept to Function

2018 Applied Spectroscopy  
The field of applied spectroscopy is strongly dominated by publications presenting proof-of-concepts, lab set-ups, and demonstrations. In contrast, the corresponding number of commercial successes of inline spectroscopy is surprisingly lower. This article discusses inline spectroscopy from an instrumentation perspective. It is the authors' firm belief that the success of inline spectroscopy lies in the understanding of how the design and implementation of the optical instrumentation affects the

This article emphasizes the need for a strong, multidisciplinary design team, whose design process is rooted in first principles, to bridge the technology "valley of death" and convert research in applied spectroscopy into commercially successful solutions. A Definition of Terms For consistency, the following glossary of terms is given: Component is used for lenses, LEDs, gratings, detectors, light sources, read-out electronics, and amplifier cards. Suppliers of optical components include Hamamatsu, Edmund Optics, Thorlabs, Excelitas, etc. Instrument can be used for spectrometers (grating-based, diffractive optical element-based, FT-IR, etc.) or hyperspectral imaging cameras. The instrument can sometimes include an integrated source. It can be general-purpose or customized for the application. Suppliers of general-purpose SINTEF Digital, Oslo, Norway
