1. A multi-stage sample recovery system comprising:
a screening array stage, wherein the screening array stage is controllable in two dimensions relative to a microscope objective with a working distance of from 0.5 mm to 25 mm and which is configured for reversible association with a screening array;
a first recovery array stage, wherein the first recovery array stage is controllable in at least one dimension relative to the microscope objective and is configured for reversible association with a recovery array;
an extraction beam generator, wherein an extraction beam is directed from below the screening array stage,
wherein the screening array stage and the first recovery array stage are controllable independently of one another.
