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 5):
The apparatus of  claim 4 , wherein the first slanted side is perpendicular to an optical axis of the scattered radiation, and when defining an angle between the first slanted side and the bottom surface as a first angle \u03b8 1 , an angle between the bottom surface and the second slanted side as a second angle \u03b8 2 , an angle between the second slanted side and the top surface as a third angle \u03b8 3  and an angle between the top surface and the first slanted side as a fourth angle \u03b8 4 , the first to fourth angles, as well as a diameter/of the first radiation-transmitting area on the first slanted side of the reflecting prism, satisfy:\n \u03b81=90\u00b0\u2212(90\u00b0\u2212theta1); \n \u03b82=180\u00b0\u22121.5\u00d7theta1; \n \u03b83=1.5\u00d7theta1; \n \u03b84=180\u00b0\u2212theta1; and \n l= 2\u00d7 d 1\u00d7tan(alpha1) \n 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  represents an object-side angle of view of the scattered radiation with respect to the reflecting prism, and d 1  denotes a distance from a center of an illumination field of view created by the illuminator on the surface of the flat panel under test to the first slanted side of the reflecting prism.
