Portable near-infrared transmittance and absorbance measurement device
Abstract
Near-infrared (NIR) light is a section of the electromagnetic spectrum just after the visible light section. The interactions with materials manifest through transmittance, absorbance, and reflectance, which provide information on their chemical properties. In this paper, a portable near-infrared measurement device was constructed to analyze the transmittance and absorbance of different samples and then compare them with literature values to check their accuracy. Results show comparable results for non-reflective samples, showing another approach to near-infrared analysis in a portable manner. The device is currently limited to transmittance and absorbance measurement for non-reflective thin solid and liquid samples.
