LMA-GDF-30/250-M, Matched Passive Double Clad Fiber

Product image of LMA-GDF-30/250-M, Matched Passive Double Clad Fiber

Coherent Large Mode Area (LMA) matched passive double clad fibers are engineered for high-power laser systems. Featuring a 30 µm core diameter and a 250 µm cladding diameter, the M version ensures low splice loss and exceptional beam quality. These fibers are matched to their active counterparts for seamless integration. The NuCOAT fluoroacrylate coating provides superior environmental durability, making them an excellent choice for industrial, medical, and defense applications.
