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.

Aerodynamic lens capable of focusing nanoparticles in a wide range

An aerodynamic lens, comprises a cylindrical body having an inlet and an outlet; and a convergence-divergence lens portion inside the cylindrical body, having a lens hole formed at the center of the convergence-divergence lens portion, through which a carrier gas and particles pass, a convergence slant surface at a convergence angle (&#x3b1;) with a central axis of the aerodynamic lens at the front of the lens hole, and a divergence slant surface at a divergence angle (&#x3b2;) with the central axis of the aerodynamic lens at the rear of the lens hole.
