980M-HP-80 Single-Mode Fiber 980-HP-80
Coherent/Nufern's 980nm high-performance single-mode fiber is a specialty fiber optimized for component manufacturers. It is suitable for components at telecommunications wavelengths, including single-mode pump laser pigtails and couplers. Cladding diameters of 125um and 80um are available. It offers improved consistency and core/cladding concentricity, specifications tighter than industry standards, and tighter tolerances on the second-order-mode cutoff wavelength. Its small bend radius is particularly suitable for miniaturized fiber-component packages. Proof testing above 200kpsi improves component reliability, while stringent specifications help manufacturers improve yield and reduce costs.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
