一种毛细管光纤参考气室
摘要：
本实用新型公开了一种毛细管光纤参考气室，包括内部中空两端密封的毛细玻璃管，所述毛细玻璃管的两端分别连接单模光纤和多模光纤，所述单模光纤和多模光纤位于毛细玻璃管内的部分均为裸纤，所述单模光纤和多模光纤位于毛细玻璃管内的部分彼此之间设有空隙。这种参考气室体积小、重量轻、结构简单、密封性好、便于制作，去除了光学准直器或高反射镜等光学器件，大大降低了成本。
摘要（英）：

The utility model discloses a capillary tube optical fiber reference air chamber. The capillary tube optical fiber reference air chamber comprises a capillary glass tube with the inside hollow and the two ends sealed, the two ends of the capillary glass tube are respectively connected with a single-mode optical fiber and a multi-mode optical fiber, the portion, located in the capillary glass tube, of the single-mode optical fiber is a naked fiber, the portion, located in the capillary glass tube, of the multi-mode optical fiber is a naked fiber, and a gap is formed between the portion, located in the capillary glass tube, of the single-mode optical fiber and the portion, located in the capillary glass tube, of the multi-mode optical fiber. The reference air chamber is small in size, light in weight, simple in structure, good in seal performance and convenient to manufacture, an optical collimator or high-reflection mirror or other optical devices are removed, and therefore cost is greatly reduced.
