0.14NA to 0.29NA GIMM

Berkshire Photonics offers a selection of graded index multimode fiber, optimized at both 850nm and 1300nm. Fibers range from standard 50/125µm up to 300µm core size, with numerical apertures ranging from 0.14 to 0.29. Custom fibers are available with different core and clad sizes, as well as custom numerical apertures. These doped core fibers are perfect for sensor and laser transmission, data communications, optical devices, and medical applications.  Benefits include high coupling efficiency, power transmission, and performance bandwidth with low attenuation.
