Description

technical field [0001] The invention relates to the technical field of ceramic ferrule detection devices, in particular to a high-precision ceramic ferrule coaxiality detector. Background technique [0002] Optical fiber ceramic ferrule is a small ceramic cylindrical tube fired with zirconia. It has a hard texture, white and delicate color, and the precision of the finished product can reach sub-micron level. It is the most commonly used and the largest number of precision positioning parts in optical fiber communication networks. , often used in the manufacture of optical fiber connectors, optical coupling of devices, etc. The accurate measurement of the concentricity of the ceramic ferrule and the smoothness of the inner hole is very important to improve the quality of the optical fiber active connector. Chinese patent (authorized announcement number is CN200972393Y) discloses a "ceramic ferrule inner diameter / concentricity measuring device", its structure includes a pair...
