10-K Zinc Lamp

Low pressure 10-k Zinc Lamps are major sources of extreme short wave UV radiation. They produce a variety of spectral lines with the strongest at 213.9nm. The lamps incorporate a special processing technique found only with BHK 10-K Zinc Lamps which offer exceptionally long life.

In addition, the 10-K Zinc Lamps are constructed with a special vacuum jacket around the double bore body and heat shield. The jacket isolates the lamp body, with the zinc 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. A high output mark on the lamp informs the user which of the two ports is to be used for maximum output.
