The D80 filber has precision grinding end face, large core diameter, air gap and sapphire D80 connector. It can transfer high power laser to 600W by single fiber. Transmission can reach more than 90% stably. The connector adopts no glue technology, which can improve the heat dissipation effect and service life, and meet the requirements of high power transmission such as laser welding and cutting.

    Product Features: 1. Sapphire D80 connector with air gap, 2. High quality stainless steel jacket, 3. Large core diameter.

    Main Application: 1. High power laser transmission, 2.L aser welding and cutting, 3. Laser marking, 4. Atmospheric spectrum measurement, 5. Laser cleaning.
