Ceramic rings are a wearing part of your fiber laser head. They insulate the heat from the nozzle and protect the laser head itself. The ceramic ring also contains an electrical contact which allows your fiber laser to perform height adjustment measurements.

Composed of a ceramic body, stainless steel part and a copper pin.

If damaged, your laser head can crash or overheat. For optimal performance and working life from your laser machine, ensure you replace the ceramic ring when recommended.
