Problems solved by technology

Since the coaxial collimator needs to complete multiple annular welding of the fiber optic adapter, adjustment ring and lens, the device needs to be positioned vertically and coaxially to facilitate the circular operation of the welding torch, and multiple annular welding also brings new coupling and detection Difficulty, the above scheme is not suitable for coupling package of coaxial collimator

Description

technical field [0001] The invention relates to the technical field of collimator packaging, in particular to a coupling welding device and method for a coaxial collimator. Background technique [0002] The collimator is an optical element used for input and output of optical fiber communication optical devices. Its structure is relatively simple, including fiber optic adapters and lenses. The divergent light emitted by the optical fiber becomes parallel light (Gaussian beam) through the front lens. To couple light into the desired device with maximum efficiency or to receive light signals with maximum efficiency. In the coaxial collimator, the fiber optic adapter and the lens are located on the same optical path line. Based on the characteristics of the parallel light output, the fiber optic adapter and the lens need to be coupled and packaged by welding the adjustment ring. [0003] Patent CN111290088A discloses a lens coupling method and device for a light-emitting eleme...
