Cal-Waste added five optical sorters in its 2020 MRF upgrade: three optical sorters on its fiber line and two on its container line. For material recovery facility (MRF) operators, fiber tends to make ...

Optical sorting technology helps material recovery facilities (MRFs) reduce their reliance on manpower to sort various materials. They are masters at sorting efficiently and quickly. Yet, as do human ...

Researchers have shown that newly designed pixel-scale metasurface lenses—flat surfaces that use nanostructures to manipulate light—can be used to make imaging sensors that are roughly three times ...

NIST scientists have devised and modeled a unique optical method of sorting microscopic and nanoscopic particles by size, with a resolution as fine as 1 nanometer (nm) for particles of similar ...
