First Claim
Patent Images
1. A collimator (33, 55, 58) panel comprising:
- a solid panel (35, 57, 60) having a first face for receiving uncollimated radiation and a second opposite face for providing collimated radiation; and
a plurality of elongate particles (37, 50) disposed in the panel and orientated to provide the collimating function.

Abstract
A collimator panel comprises: a solid panel having a first face for receiving uncollimated radiation and a second opposite face for providing collimated radiation; and a plurality of elongate particles disposed in the panel and orientated to provide the collimating function. A method of manufacturing a collimator panel comprises the steps of: suspending a plurality of elongate particles in a liquid; applying an electric or magnetic field to the suspension to orientate the particles; and solidifying the liquid to fix the orientation of the particles, thereby forming a collimator panel. A method of manufacturing the elongate particles is also provided.

32. A method of manufacturing elongate particles (69) for suspending in panels, the method comprising the steps of:
-
depositing a patterned layer of negative etch resist material (61) on a layer of elongate particle material (63), patterned areas representing a required shape and size of a plurality of elongate particles (69); and etching areas of the layer of elongate particle material not covered by the negative etch resist material, thereby leaving elongate particles. - View Dependent Claims (33, 34, 35, 36)

37. A method of manufacturing elongate particles for suspending in panels, the method comprising the steps of:
-
depositing a patterned layer of positive etch resist material on a layer of elongate particle material, unpatterned areas representing a required shape and size of a plurality of elongate particles; processing the unpatterned areas to make them more etch resistant than the patterned areas; and removing the positive etch resist material and etching areas of the layer of elongate particle material that were covered by the positive etch resist material, thereby leaving elongate particles. - View Dependent Claims (38, 39, 40)
