A known lamp module for spectral analysis devices includes a lamp receptacle body having a cavity for receiving a deuterium lamp having a lamp bulb made of synthetic quartz glass. The cavity has a beam outlet opening closed with an optical transmission element. In order to provide a lamp module having a deuterium lamp with an ozone filter that exhibits a long service life, that can be manufactured economically, and that ensures a high intensity in a wavelength range between 190 nm and 250 nm, such a known lamp module is provided with a VUV edge filter in the beam outlet opening on the side of the optical transmission element facing the deuterium lamp.

Lamp module, particularly for spectral analysis devices

A gas-discharge lamp (deuterium lamp) is provided having a lamp bulb () filled with gas, an anode () disposed inside the lamp bulb, a cathode () spaced from the anode inside the lamp bulb, a housing having a molded body (), a rear housing wall (), and a housing base made at least partially of electrically nonconductive material. The housing base includes a housing front (), an intermediate housing wall (), a cathode space (), and a cathode shielding window (). The cathode shielding window is insulated from the molded body and/or is made of an insulating material. The gas-discharge lamp is particularly applicable for analytical purposes.
