Gas discharge lamp, more particularly deuterium lamp

Gas discharge lamp, in particular deuterium lamp, having a gas-filled lamp bulb which surrounds an electrode insert, wherein the electrode insert comprises:

• (a) a partition wall made of an electrically insulating material,
• (b) a cathode-side assembly mounted on a front side of the partition wall and comprising a cathode, a cathode window and a light emission window,
• (c) an anode-side assembly mounted on a rear side of the partition wall, comprising an anode and at least one diaphragm, which with the light emission window defines an optical axis along which a radiation generated by discharge is emitted from the light emission window,
• wherein at least the anode and the at least one diaphragm are combined to form a component ensemble, and wherein at least one retaining profile for retaining the component ensemble projects from the rear side of the partition wall.
