notes: label: Description
content: Walther Nernst, a scientist working at Goettingen University, introduced the Nernst Lamp (or Glower) in 1897. In place of the usual tungsten filament, this design used a ceramic rod heated to incandescence. In time, the form proved to be useful as the light source for Infra-Red spectroscopy. This example was used with the Perkin-Elmer Model 21 IR spectrometer in the collection. The inscription on the jar holding it reads "021-0398 / Part Number / Perkin-Elmer Corporation."
