Abstract
The invention relates to an optical device and an optical process for displacement of particles (P). The device comprises a substrate (6) on which at least one strip (5) of at least one thin layer is deposited, the strip (5) having an optical thickness gradient along an axis such that the displacement of a particle (P) takes place along this axis when an electromagnetic wave (L) illuminates the device. The invention is applicable to sorting and/or analysis of particles.
Claims22
Optical device for displacement of particles (P) characterized in that it comprises a substrate (6) on which at least one strip (5) of at least one thin layer is deposited, the strip (5) having an optical thickness gradient along an axis such that the displacement of a particle (P) takes place along this axis when an electromagnetic wave (L) illuminates the device.
Optical particle displacement process along an axis, characterized in that it comprises the formation of a stationary wave intensity gradient at a particle to be displaced, by illumination, using an electromagnetic wave, of a substrate (1) on which at least one strip (5) is deposited, comprising at least one thin layer with an optical thickness gradient along the axis.
