Spero® Quantum Cascade Laser-Based IR Microscopy

Daylight Solutions


Microplastic Imaging with QCL-Based IR Microscopy

Microplastics analysis is a rapidly evolving field of research that aims to identify and quantify microplastics particles (MPPs)–and their effects on the ecosystem–in a wide range of environments including soil, waterways, and the human body. Given the strong interest in MPPs, several spectroscopic tools are being used to study MPPs, including IR spectroscopic and IR microspectroscopic (imaging) techniques. Daylight Solutions designs and manufactures a range of advanced infrared quantum cascade (QCL-IR)-based laser sources and instrumentation ideally suited to MPP research, which typically requires rapid analysis of large sample volumes. The Spero® QCL-IR microscope, for example, uses the high brightness of its QCL-IR light engine to enable real-time, wide-field IR imaging (up to 2mm x 2mm FOV), and collect full IR hyperspectral data cubes in tens of seconds. A recently published paper by Alfred Wegener Institute (Helgoland, Germany) demonstrates how this performance is bringing new, powerful analytical capabilities to MPP analysis.
