  • Assures maximum stability and lifetime of lamp

   Optimum UV Illumination for Fiber Optics


The ASBN-D130/230 is a deep UV ultraviolet deuterium light source for the 180-400nm (max. 160-400nm) region. It has been designed to provide the maximum possible illumination either directly or through an optical fiber.
The ASBN-D130 consists of one 30 watt deep UV deuterium lamp, a housing and a regulated power supply. The housing contains a 1" quartz doublet (f#/1.0, 1X) assembly for maximum possible illumination to the optical fiber.
The ASBN-D230 consists of two 30 watt deep UV deuterium lamps, a housing and two regulated power supplies. The housing contains two 1" quartz doublet (f#/1.0, 1X) assemblies. One is for focusing the second deuterium lamp on the first lamp and the other is for maximum possible illumination to the optical fiber. The first deuterium lamp has a "see-through" hole to allow the light from a secondary source to pass through the same light path as the first one.
The 30 watt deuterium lamp used in the ASBN-D130/230 has an average lifetime of 1,000 hours under regulated conditions. The life end is defined as the time when the UV region radiant intensity falls below 50% of its initial value or when output fluctuation exceeds 0.03%.
The power supply provided with the ASBN-D130/230 is a dc current regulated one. This assures maximum stability and lifetime of the lamp.
