ALEXANDRIA, Va., April 7 -- United States Patent no. 12,596,064, issued on April 7, was assigned to SYMPATEC GMBH (Clausthal-Zellerfeld, Germany).

"Dynamic 3D light scattering particle size distribution with offset polarization beams" was invented by Daniel Werner (Goslar, Germany).

According to the abstract* released by the U.S. Patent & Trademark Office: "A dynamic 3D light scattering particle size distribution measurement device includes a polarization splitter for generating an s laser beam with perpendicular polarization and a p laser beam with parallel polarization that travels parallel to and spaced apart from the s laser beam. A lens is used to focus the s laser beam and the p laser beam onto a common focus area inside a sample ho...
