Low pressure Zinc Lamps are major sources of extreme short wave UV radiation. They produce a variety of spectral lines with the strongest at 213.9 nm. The lamps incorporate a special processing technique. Zinc Lamps offer an exceptionally long life, In addition, are constructed with a special vacuum jacket around the double bore body and heat shield.
