FANAL - S.A. Fabrique Nationale de Lampes électriques Enghien & Bruxelles (Belgique) constituée en 1919.

Application/Use: Oscillograph source.

The oscillograph has long been a useful instrument in the analysis of electric currents of all sorts, and also as an instrument of sound-analysis, particularly in cases where fine differences in timbre are important determinants of the tone-quality.

The filament of the lamp is kept straight by a spring. This geometry allows the light to be imaged well on the entrance slit of the instrument.
