Description

technical field

[0001] The invention belongs to the field of optical fiber fusion splicing, in particular to a manual pre-matching device for an objective lens of an optical fiber fusion splicing machine. Background technique

[0002] In the fiber splicing process, in order to achieve high-quality fiber splicing, two high-definition microscope objectives are needed to ensure the accurate alignment of the fiber core. Use in pairs for better core alignment.

[0003] At present, the two objective lenses on the fusion splicer are installed on the fusion splicer first, and then paired. After installation and debugging, if it is found that the two objective lenses cannot be matched, it is necessary to remove and replace the objective lens, sometimes even several times. Matching two objective lenses, this process has brought great difficulties to the production and debugging personnel, and is very time-consuming. Contents of the invention

[0004] In order to solve the problems...
