Low pressure Zinc and Cadmium lamps are major sources of extreme short wave UV radiation. They produce a strong spectral line source at 213.9 nm for Zinc and 228.8 nm for Cadmium. Zinc and Cadmium Lamps are commonly used in air pollution monitoring and sulphur dioxide(SO2) detection systems.

The lamps are constructed using a special vacuum jacket around the double bore lamp body and heat shield. The jacket isolates the lamp body, with the zinc or cadmium arc, from the external environment. This gives the lamp body excellent temperature stability resulting in very low noise and steady lamp intensity that is relatively independent of external temperature fluctuations.
The radiance from the lamp comes from two ports located on opposite sides of the lamp. This radiance can be used from both ports simultaneously, from a single port, and from any portion of the arc.
Lamps are available with either radial or axial lead wire configurations and Silicon or Delrin end caps. Choose from a number of lead wire and lead termination options as shown in the Datasheet. For OEM applications BHK can design custom lead and connector terminations.

Long life 10-K Zinc Lamps offer the same high performance as our standard Zinc Lamps, but special processing allows for longer lifetimes. Warranties of 2,500 or 10,000 hours are offered, depending on your application / use.
