title: Micro-particle sorting by Newton-ring device.
abstract: A Newton-ring micro-particle sorter was constructed from a small convex lens and a flat glass. The sub-micrometer gap between them was controlled by a piezo-actuator and utilized for the fractionation of very small amounts of micro-particles in liquid.
