| High-stability, long-life, and high-intensity deuterium lamp

Excelitas’s New Deuterium Lamp D ₂^plusBy leveraging new materials and process technologies, this product combines a service life of over 2,000 hours with exceptional output stability and intensity throughout its entire lifespan. This sets it apart from other long-life lamps currently available on the market and makes it particularly well-suited for high-end (U) HPLC instruments or UV-Vis spectrophotometers.

| 30W Deuterium lamp: Perfect match

Excelitas new generation D ₂^plusDeuterium lamps are used for various needs and applications:

· Excelitas High-transparency synthetic quartz glass shell D ₂^plusAdopt “enhanced life performance” ( ELP ) The remaining luminous intensity maintained at the end of the service life is standard. D ₂ Twice the lamp. ELP The coating can effectively protect the luminescent element, preventing degradation caused by vacuum ultraviolet radiation and reactive plasma components.

· All D ₂^plusThe deuterium lamp provides a transmission-type light window.

The transmission-type optical window allows tungsten-halogen lamps and deuterium lamps in the optical system to be arranged in a straight line. This approach enables simplification and cost reduction of UV-Vis spectrophotometers—for instance, eliminating the need for moving mirrors or half-silvered, half-transparent beam splitters. The transmission-type optical window design... D ₂^plusDeuterium lamps offer exceptional high stability, as well as a variety of filament voltages and aperture sizes.

· Offer different spectral ranges

D ₂^plusThe deuterium lamp can be optionally equipped with a UV glass bulb (cut-off wavelength 185 nm) or a high-transmittance quartz bulb (cut-off wavelength 160 nm), offering enhanced performance tailored to your application or instrument design.

| A stable analytical lamp ensures accurate analysis and measurement.

Your customers require precise, reproducible analytical procedures and reliable results, making the use of a dependable, long-lasting light source absolutely essential. High-quality qualitative lamps are precisely the solution you need.

The analysis and measurement of gases, liquids, or solids must be as precise as possible to obtain accurate results. Common techniques include absorption, reflection, projection, fluorescence, and ionization.

To develop high-quality analytical instruments for these processes, it is essential to have light sources that are perfectly matched to the instrument’s performance. Heraeus Specialty Light Sources has developed deuterium lamps, hollow-cathode lamps, and other specialized light sources specifically tailored for these instruments. These light sources are designed not only to extend lamp life and reduce the overall cost of ownership of the system but also to achieve the highest possible repeatability and accuracy, enabling users to benefit from consistent, sensitive, and stable analyses.

After years of effort, Esselida A light source technology has been developed to meet the growing demand from instrument manufacturers for ultra-low detection limits and high sensitivity.

| Deuterium lamp power supply

Deuterium lamps must meet stringent requirements for noise levels, long-term stability, and operational lifespan. The power supply should not limit or degrade the performance of the light source. Therefore, Heraeus offers a specially developed, independently designed power supply based on its existing deuterium lamp technology.

Hella Power Sources stand out due to their stable electrical parameters and exceptionally reliable ignition circuit, which not only protect the light source but also extend its operational life and ensure dependable startup.
