Abstract: A surface inspection system, as well as related components and methods, are provided. The surface inspection system includes a beam source subsystem, a beam scanning subsystem, a workpiece movement subsystem, an optical collection and detection subsystem, and a processing subsystem. The optical collection and detection system features, in the front quartersphere, a light channel assembly for collecting light reflected from the surface of the workpiece, and a front collector and wing collectors for collecting light scattered from the surface, to greatly improve the measurement capabilities of the system. The light channel assembly has a switchable edge exclusion mask and a reflected light detection system for improved detection of the reflected light.

Abstract: A method for inspecting a surface of a workpiece for asymmetric defects, by scanning an incident beam on the surface of the workpiece to impinge thereon to create reflected light extending along a light channel axis in a front quartersphere and scattered light, the incident beam and the light channel axis defining an incident plane, collecting the scattered light at a plurality of collectors disposed above the surface at defined locations such that scatter from asymmetric defects is collectable by at least one collector, detecting collector output and generating signals in response, and processing the signals associated with each collector individually to obtain information about asymmetric defects.
