With the development of China's optical communication industry,higher requirements for dimensional inspection have been put forward for multi-core high-density connectors(such as MPO and MT),the core pitch of FA fiber arrays,and the pitch of VG V-groove substrates.Traditional measurement methods are inefficient and lack sufficient accuracy,while this equipment can perform automatic measurement with a repeat accuracy of ≤0.1 μm,effectively solving this problem.The equipment is available in two models:YGN-590-FAVG and YGN-590-MT.Using our equipment for inspection can significantly improve the accuracy of optical fiber connections.It has a wide range of application fields,including the optical communication industry and the semiconductor industry.
