Paper Abstract

Micron-sized particles can be trapped by means of a highly focused beam; light is concentrated in a tiny spot using a high numerical aperture objective. In this communication we describe a numerical tool we have developed for obtaining the force exerted by a beam on a spherical dielectric particle in realistic conditions. The system (a water immersion microscope objective) is simulated using an optical system design software that provides the required information to feed the application. The calculation of the force is carried out using the ray-optics (Mie) approach.
