Deuterium Lamp, Optical System : Double Beam

A deuterium lamp is a type of gas discharge lamp that emits a continuous spectrum of ultraviolet (UV) light, ranging from approximately 160 to 400 nanometers. It contains deuterium gas, a heavier isotope of hydrogen, which, when electrically excited, emits UV radiation. Deuterium lamps are commonly used as light sources in UV-visible spectroscopy, particularly in high-performance liquid chromatography (HPLC) detectors, due to their stable output and broad UV range. The emitted light is utilized for quantitative and qualitative analysis of various compounds, as many substances absorb UV light at specific wavelengths. These lamps are favored for their long lifespan, low noise, and consistent intensity, making them essential in scientific research, environmental monitoring, and quality control processes in various industries.
