HPK 125W high-pressure mercury vapor lamps (previously Philips HPK 125W) from Heraeus No-
blelight are suitable for use in scientific instrumentation and other applications requiring high sta-
bility UV radiation combined with an accurate position for the arc.
The HPK 125W mercury lamp can be used for applications such as photochemical processing, fluorimetry, mercury analysers, medical and environmental equipment and fixed wavelength detectors.
HPK 125W lamps provide maximum energy at 365 nm, with substantial radiation also at 435, 313, 253 and 404 nm. In addition, there is a continuum from 200 to 600 nm, peaking at 260 nm with approximately 20 % of the maximum energy measured in the line spectrum.
