Auslöschlampe

Auslöschlampe is a German term that translates to "extinguishing lamp" or "quenching lamp." It refers to a specific type of lamp used in scientific and industrial applications, primarily for the purpose of absorbing or nullifying unwanted light. This is often achieved by incorporating specific filters or materials within the lamp's construction that absorb certain wavelengths of light while allowing others to pass through.

These lamps are not designed to provide illumination in the traditional sense. Instead, their function is to selectively remove or reduce light of specific frequencies from a light source. This can be crucial in experiments where stray light of certain wavelengths could interfere with measurements or reactions. For example, in spectroscopy, an auslöschlampe might be used to remove background radiation or unwanted spectral lines.

The specific design and materials used in an auslöschlampe vary depending on its intended application. Some may utilize chemical coatings, while others employ physical filters. The principle behind their operation is based on the absorption spectra of the materials used. By carefully selecting these materials, a lamp can be designed to absorb a very narrow band of wavelengths or a broader spectrum. Their use is generally confined to specialized laboratory settings and industrial processes requiring precise control over light conditions.
