Description
The Heraeus Noblelight HPK125W is a 125 watt (125W) high pressure mercury lamp for use in scientific instrumentation and other applications requiring high stability UV radiation combined with an accurate position for the arc. The light output from the high pressure lamp provides 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 600nm, peaking at 260nm with approximately 20% of the maximum energy measured in the line spectrum. The HPK125W is 91 mm overall length, with a 31.5 mm arc gap and a BA15D bayonet base. Also known as Cathodeon HPK125W and 80017490. The HPK125W mercury lamps are also suitable as light source in the Hilger Model FS146 Mk2 Spectrograph and in instruments that utilize Philips lamp types 9280781051 and 93110.
