These are specialized low-pressure gas discharge lamps essential for optics and quantum physics experiments requiring a monochromatic (single color or narrow band) or highly specific light source. The lamps contain pure elements (either Sodium vapor or Mercury vapor) which, when electrically excited, emit light at their characteristic spectral wavelengths. Sodium lamps are commonly used to produce a highly monochromatic yellow light, ideal for experiments like Newtons Rings or Polarimetry.
Monochromatic Source: Sodium lamps provide a highly monochromatic, bright yellow light, simplifying optical measurements in interference and diffraction experiments.
Spectral Calibration: Mercury lamps emit multiple distinct and sharp spectral lines, making them indispensable for calibrating spectroscopes and diffraction gratings.
High Intensity: The lamps are designed to produce a high intensity light output for easy visualization and accurate measurement in laboratory settings.
Long Lifespan: Built with durable glass envelopes and robust electrodes to ensure a long operational life and consistent spectral output over many uses.
Easy Integration: Designed to plug easily into a dedicated lamp power supply unit, which is required to provide the high voltage necessary for lamp ignition and stable operation.
Lamp Type: Low pressure vapor discharge lamp.
Fill Gas: Available as pure Sodium vapor (Na) or pure Mercury vapor (Hg).
Required Power: Requires a dedicated High Reactance Ballast or Power Supply with specific starting and operating voltage requirements.
Wattage: Typically low power, in the range of 35 Watts to 100 Watts, optimized for lab use.
Base Type: Standard bulb base or specialized laboratory socket base for secure connection to the power unit.
