Deuterium lamps (D2) are light sources that use an arc discharge in low pressure Deuterium gas. They emit an intense spectrum in the UV region, delivering unsurpassed stability performance. The lamps offer long lifetime (2,000 hours typ.), excellent stability and high spectral UV-VIS throughput for applications such as UV absorbance, liquid chromatography, capillary electrophoresis, peptide synthesis, water analysis, etc…

To achieve optimum performance, lifetime and stability, Deuterium lamps need to be carefully integrated in well-designed housings and driven by adequate power supplies.

tec5USA has developed opto-mechanical modules and specific drive electronics to operate these lamps in the most efficient manner, incorporating them in our modular spectroscopy instrumentation and in our online analyzer turnkey solutions.
