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 3):
The apparatus of  claim 1 , wherein the beam trimmer comprises a reflecting prism with an outer surface of the reflecting prism defining a first radiation-transmitting area, a second radiation-transmitting area and an outer radiation-reflecting area, the first radiation-transmitting area, the second radiation-transmitting area and an inner radiation-reflecting area of the reflecting prism together constituting the first optical member, the first radiation-transmitting area facing toward the scattered radiation, the second radiation-transmitting area facing toward the detector, the reflecting prism configured for directing the scattered radiation to pass through the first radiation-transmitting area onto the inner radiation-reflecting area and further directed by the inner radiation-reflecting area to pass through the second radiation-transmitting area onto the detector, the outer radiation-reflecting area on the outer surface of the reflecting prism corresponding to the reflected radiation and constituting the second optical member, the reflected radiation being incident on and reflected by the outer radiation-reflecting area so as not to be received by the detector.
