mrad liegt, durch eine Platinbeschichtung auf 4,5 mrad erhöht werden. Dies schlägt sich wiederum vorteilhafterweise auf die Transmission der Röntgenstrahlung nieder. Alternativ ist denkbar, daß bei dem Einsatz von beschichteten Reflexionsflächen der Grundwerkstoff aus einer Quarzoberfläche oder einem Kunststoffmaterial bestehen kann, welches die Anforderung an die Ebenheit erfüllt und eine Beschichtung aufweist. Vorteilhafterweise kann die Beschichtung zumindest am Eingang der Reflexionsflächen 18 vorgesehen sein, so daß die Anzahl der eingefangenen und reflektierten Strahlen möglichst groß ist. Über den Verlauf entlang der Reflexionsflächen 18 kann die Beschichtung vollständig fortgeführt werden oder auch nur teilweise vorgesehen sein. Ebenso kann sich die Beschichtung bzw. das Material der Beschichtung in Abhängigkeit der Anwendungsfälle auch ändern. Beispielsweise kann durch Verkleinerung des Grenzwinkels für die Totalreflexion die Divergenz am Ausgang der Reflexionsflächen 18 verkleinert werden, wodurch eine Fokussierung der Strahlung und dadurch eine Intensitätserhöhung auf dem Meßbereich 24 des Meßobjektes 16 erzielt werden kann. Dazu ist beispielsweise denkbar, daß in einem Bereich nahe dem unteren Ende 22 der Reflexionsfläche 18 eine Beschichtung nicht vorgesehen ist oder eine die Totalreflexion verhindernde Beschichtung vorgesehen ist, wodurch die unterhalb der Reflexionsfläche 18 austretende Strahlung gerade auf die Größe des Meßbereiches 24 von dem Meßobjekt 16 fokusiert ist. Die Bestrahlung von Randbereichen außerhalb des Meßbereiches 24 kann dadurch erheblich verringert werden.
