All the tubes are manufactured in the Soviet Union and can have a quality mark and other factory marking on the case. You can look all details at the original photos.
Lamp deuterium spectral arc D2(D) (legacy name DDS 30) is used as a source of continuous ultraviolet (UV) radiation in the wavelengths 186-360 nm in different spectral machines and devices for industrial purposes: the spectrophotometer SF-46, SF-56 and SF-256, monochromators, special lights and appliances for testing the above equipment.
Lamp deuterium 30 DDS (D2, D) is a cylindrical flask with side window made of optical quartz and has actally base. Connection diagram (Pinout): 3 — cathode screen; 5 — cathode; 7 — anode (the remaining unoccupied is prohibited to use as reference points for installation). Please see attached photos.
Before ignition it is recommended to wipe the window of the tube with cotton, moistened with medical alcohol, to clean the window surface from contamination. When working with the included deuterium lamp DDS 30 (D2 D) should be wearing safety goggles for protection of eyes from UV rays.
