Fiber Scrambler/De-Speckler – 10kHz Voice-Coil

The Optical Fiber Mode Scrambler/De-Speckler (FMSC) is engineered to scramble laser light modes in multimode fibers, eliminating modal interference without optical loss. As laser light propagates through a multimode fiber, the beam shape or mode field fluctuates with time and distance, causing signal instability. The FMSC resolves this by redistributing the mode field with modulation up to 10 kHz, ensuring a stable, homogeneous laser output ‒ essential for applications requiring uniform beam quality. Ideal for measurement and sensor systems, the FMSC enhances accuracy despite environmental variations. In many fiber-coupled applications, reducing speckle is crucial, as modal noise can degrade performance.
