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 8):
The apparatus of  claim 7 , wherein: an angle \u03b8 5  between the first reflector and the flat panel under test satisfies \u03b8 5 =180\u00b01.5\u00d7theta 1 ; the second reflector is disposed on a same line as the third reflector and is closer to the flat panel under test with respect to the third reflector; the second reflector and the third reflector are both oriented at an angle \u03b8 6  with respect to the flat panel under test, which satisfies \u03b8 6 =180\u00b0\u2212theta 1 ; and a lengthwise dimension of the first reflector is greater than 2\u00d7d 1 \u00d7tan(alpha 1 ), a lengthwise dimension of the second reflector is greater than 2\u00d7(d 1 +d 3 )\u00d7tan(alpha 1 ) and a lengthwise dimension of the third reflector is greater than 0 and smaller than 2\u00d7(h 1 \u2212h 2 ), where theta 1  denotes an angle between the optical axis of the scattered radiation and the normal of the surface of the flat panel under test; alpha 1  denotes an object-side angle of view of the scattered radiation with respect to the first reflector; d 1  denotes a distance from a center of the illumination field of view created by the illuminator on the surface of the flat panel under test to an optical axis of the second reflector extending along a propagation direction of the scattered radiation; h 1  denotes a distance from a location of the third reflector stricken by the reflected radiation to the flat panel under test, which satisfies h 1 =d 2 /tan(beta); h 2  denotes a distance from a highest intersection point between the scattered radiation and a line that is perpendicular to the flat panel under test and passes the location of the third reflector stricken by the reflected radiation to the flat panel under test, which satisfies h 2 =d 2 /tan(theta 1 /alpha 1 ); and beta denotes an angle between the normal of the surface of the flat panel under test and the radiation beam.
