Description
In the late 1890s, a German scientist named Walter Nernst designed an incandescent lamp that used a ceramic rod (rather than a tungsten filament) heated to incandescence. After Nernst lamps fell into disuse, scientists found that Nernst glowers would serve as infrared sources for spectroscopy. This example came with the Model 21 Perkin-Elmer spectrophotometer in the collection. It is contained in a plastic jar marked “021-0398 / Part Number.”
