    Description

    Hollow cathode lamps are metal-vapor discharge lamps developed for analysis by atomic absorption spectroscopy. This analysis requires a special lamp for each element to be measured. The lamps have a special design, described in Wikipedia. A thorough list of different chemical elements and their spectral lines generated by the hollow cathode lamps is given by Hamamatsu's sites. This particular lamp is vintage and was made in former East Germany, years 70', by the bulb company NARVA, today part of Philips.
    The lamp type is CaHK and its element is calcium (Ca) with its specific maximum of the absorption analysis line at 422.67 nm (after Hamamatsu site). The lamp is new, in pristine condition, never used, with original, opened box. It is intended for spectroscopic laboratories, or as a vintage, collectible item.
