Abstract:
An apparatus for detecting a degree of particulate contamination on a flat panel is disclosed, including: an illuminator for producing a radiation beam which results in scattered radiation from its scattering by contaminants on a surface of the flat panel under test and reflected radiation from its reflection by the surface of the flat panel under test; a detector for collecting the scattered radiation, the detector having a radiation collection surface perpendicular to a normal of the surface of the flat panel under test; and a beam trimmer for separating the reflected radiation from the scattered radiation, the beam trimmer including a first optical member, disposed in correspondence with the scattered radiation and configured for directing the scattered radiation to be collected by the detector, and a second optical member disposed in correspondence with the reflected radiation and configured for directing the reflected radiation not to be collected by the detector.

Claim (Index 4):
The apparatus of  claim 3 , wherein: the reflecting prism has a cross-section in a shape of a trapezoid with a top surface, a bottom surface, a first slanted side and a second slanted side; the top surface and the bottom surface are parallel to the surface of the flat panel under test; the bottom surface is closer to the detector with respect to the top surface; the first slanted side defines the first radiation-transmitting area corresponding to the scattered radiation; the bottom surface defines the second radiation-transmitting area; and the scattered radiation enters the reflecting prism through the first slanted side and is first incident onto and reflected by an inner surface of the second slanted side of the reflecting prism and then incident onto and reflected by an inner surface of the first slanted side so that the scattered radiation exits the reflecting prism through the bottom surface and is finally collected by the detector.
