A development aimed at extending the life of a tungsten filament. The iodine vapor in the lamp envelope combines with the tungsten vapor emitted by the hot filament, but the compound is decomposed by the heat and deposits the tungsten back onto the filament itself. The lamp envelope must run hot.

The Transistor’s Optical Cousin
Bandpass filters are passive optical devices that control the flow of light, much as transistors control electricity but are active devices. They can be used either to isolate certain wavelengths or colors, or to control the wavelengths reaching a detector. Applications range from detecting the gaseous composition of a distant star to determining the chemical activity in a human cell. In their earliest form, bandpass filters were constructed of absorbing media in a solute, such as water or...
