Abstract

Recycling is an important issue contributing to economy and ecology. Material sorting is required to discriminate different raw substances. Near infrared spectroscopy is a suitable tool for the analysis of organic matter like plastic waste or textiles. A new design for a miniaturized MEMS based scanning mirror micro spectrometer has been realized for measurements in the 1000 nm to 1900 nm region offering 10 nm resolution. Test measurement in application close use cases have been performed resulting in promising data for different kind of plastic and textile samples.
