AERODYNAMIC LENS CAPABLE OF FOCUSING NANOPARTICLES IN A WIDE RANGE

摘要

An aerodynamic lens includes a cylindrical hollow body having an inlet and an outlet, and first and second focusing parts formed in the body. The first focusing part includes a plurality of orifice lenses of which inner diameters (df) are gradually decreased in an advancing direction of particle. The second focusing part includes a plurality of orifice lenses of which inner diameters (df) are gradually increased in the advancing direction of particle.
