Coated Fibre

Coated fibre is a kind of large core diameter fibre designed specifically for energy transmission. Through precision polishing, high-quality cleaning, and targeted coating curve design, it can achieve high transmittance and low heat absorption fibre coupling. It has the characteristics of good cleanliness of end face, high reliability of film layer, targeted optimization of coating curve, etc. It is suitable for industrial laser pump, medical cosmetology, optical fibre sensing and other applications.

Applications
  • Pump source tail fibre
  • Optical fibre sensor
