Abstract: Automated manufacturing in the fiber optics industry has introduced a series of new problems due to the small size of the parts being assembled and the precise optical alignments required. However, processes requiring the manual assembly of parts using glue are slowly being replaced by automated processes involving the laser welding of metallically encased optical parts. Unfortunately, almost every step in the process causes a small degree of misalignment, which may cause the device to fall below transmission standards. The present invention provides a method of assembling an optical device which includes special steps that involve re-aligning the elements in the optical device after other steps in the method have caused a misalignment. In particular, the method of the present invention includes testing the alignment of the optical elements at several stages throughout the assembly process, and applying addition asymmetric welds to the finished product to improve the transmission results.

Abstract translation: 光纤行业的自动化制造引起了一系列新的问题，因为要组装的部件的尺寸小，需要精确的光学对准。 然而，需要使用胶水手工组装零件的工艺正在缓慢地被包括金属封装的光学部件的激光焊接的自动化过程所取代。 不幸的是，该过程中几乎每一步都会导致小的失准，这可能导致设备降低到传输标准之下。 本发明提供一种组装光学装置的方法，其包括在该方法中的其它步骤引起未对准之后包括在光学装置中重新对准元件的特殊步骤。 特别地，本发明的方法包括在整个组装过程中在几个阶段测试光学元件的对准，以及对成品施加附加的不对称焊接以改善透射结果。
