PCT No. PCT/EP90/00114 Sec. 371 Date Sep. 10, 1990 Sec. 102(e) Date Sep. 10, 1990 PCT Filed Jan. 20, 1990 PCT Pub. No. WO90/09032 PCT Pub. Date Aug. 9, 1990.A deuterium lamp with a quartz glass bulb for spectral analyzers is disclosed. At least the portion of the quartz glass bulb through which the radiation produced passes is provided on its outer surface with a multiple interference filter layer; the physical layer thickness of each layer is in the range from 10 to 70 nm. The multiple layer comprises atlternating aluminum oxide and silicon dioxide, or magnesium fluoride. The interference filter layers are preferably vapor-deposited in a vacuum.
