80-2049-2 Double-Bore笔形汞灯采用特殊结构设计，去除了悬挂的引线，将引线全部集中于灯管一端，该特性非常适合将灯管浸入液体，或将灯插入小孔等应用。

双孔灯管具备高强度独立谱线，各谱线之间区分度良好，汞灯在工作中不会产生污染物，Jelight公司在生产工艺中采用特定的烧结工序，确保每一支灯管内部无杂质污染，这些工艺提升了灯管的品质、工作稳定性、发光均匀度以及使用寿命。
81-3306-1笔形汞灯不含臭氧185nm波段

由于该灯管工作稳定性极高，这一点对于需要精确校准的仪器和设备应用至关重要，与其他紫外线光源相比，双孔汞灯点燃温度极低，通常不超过100°C。

双孔汞灯灯泡是耐用的紫外光源，在理想条件下使用寿命可达5000小时，所有的双孔汞灯泡都可以填充各种气体，如氩气、氪气、氖气、氙气和氦气。

同时提供供电电源：24V电源模块，12V电源模块，220V供电电源。

The specialized design of this mercury bulb eliminates dangling lead wires because of their location at only one end of the lamp. This feature is ideal for such applications as submerging the lamp into a liquid or inserting the lamp into small apertures. The double-bore has strong isolated spectral lines that are well separated from the others, and the bulbs are free from contaminates which are harmful to the operation of the lamp. Jelight Company takes extra, unique steps in the manufacturing process to ensure that each lamp is free of contamination. These processes improve the quality, stability, uniformity, and lifetime of the lamps. When operated properly, the lamp is extremely stable which is important for accurate calibration and instrumentation applications where this stability is vital. In comparison to other UV light sources, the double-bore lamps are very cool burning; the temperature rarely exceeds 100° C. This is important in processes where the components or substances must not be heated by the light source used.

The double-bore mercury bulbs are long lasting UV light sources with a lifetime of 5000 hours under optimal conditions. However, some lamps have operated continuously for as long as 30000 hours. All of the double-bore bulbs can be filled with a variety of gases such as argon, krypton, neon, xenon, and helium.
