Abstract

Eine elektrodenlose Niederdruck-Entladungslampe (1), insbesondere Deuteriumlampe, weist einen zylindersymmetrischen Blendenkörper (2) auf, der an seinen Stirnseiten (8,9) jeweils einen Hohlraum (4,5) enthält; die beiden Hohlräume (4,5) sind durch eine Bohrung (7) miteinander verbunden, welche als Blendenöffnung dient, um das mittels Einkoppelung eines hochfrequenten elektromagnetischen Feldes im Inneren erzeugte Plasma zwecks Intensitätserhöhung der abgegebenen Strahlung einzuschnüren. Beide Stirnseiten (8,9) des zylindersymmetrischen Blendenkörpers (2) sind mit einer hermetischen Abdichtung versehen, von denen wenigstens eine als Austrittsfenster (11) ausgebildet ist; in einer bevorzugten Ausführungsform erfolgt die Einkoppelung des elektromagnetischen Feldes auf kapazitivem Wege durch auf den Stirnflächen befindliche Elektroden (13,14), die wenigstens eine Öffnung (15) für den Austritt der Strahlung aufweisen, sofern sie benachbart zu einem Austrittsfenster (11) angeordnet sind.
