Abstract
A gas-discharge lamp (deuterium lamp) is provided having a lamp bulb (26) filled with gas, an anode (12) disposed inside the lamp bulb, a cathode (10) spaced from the anode inside the lamp bulb, a housing having a molded body (18), a rear housing wall (24), and a housing base made at least partially of electrically nonconductive material. The housing base includes a housing front (16), an intermediate housing wall (22), a cathode space (28), and a cathode shielding window (20). 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.
