Patent ID: 7504622

Claim:
A high-throughput inspection system, comprising: a charged particles to light converter adapted to convert a secondary array of charged particle beams to a first array of light beams; wherein the first array of light beams is characterized by a first ratio of an average first array light beam diameter to an average distance between adjacent first array light beams of the first array; first optics, positioned between the charged particles to light converter and between inputs of multiple fibers, wherein the first optics is adapted to provide a second array of light beams; wherein each second array light beam corresponds to a first array light beam; wherein the second array of light beams is characterized by a second ratio of an average second array light beam diameter to an average distance between adjacent second array light beams; wherein the second ratio is substantially smaller than the first ratio; multiple fibers that are adapted to direct second array light beams towards multiple detectors; wherein the inputs of the multiple fibers are positioned in response to an expected spatial disorder of the second array of light beams and to diameters of second array light beams; and multiple detectors, adapted to detect light from the multiple fibers.
