Passive Fiber Mode Scrambler/De-Speckler

SKU: PFMS

The PFMS is an all-fiber passive mode homogenizer designed to overcome the modulation speed limitations of mechanical mode scramblers and to operate reliably with high-power pulsed lasers. Leveraging a proprietary patent-pending design, the PFMS incorporates a mode-homogenizing element between two multimode fibers to redistribute the optical field within the fiber core. This passive scrambling process stabilizes the beam profile and suppresses modal interference. In multimode fibers, mode field fluctuations can introduce signal instability, speckle, and modal noise. The PFMS eliminates these effects by delivering a stable, homogeneous output, ensuring accurate and repeatable results. It is ideally suited for applications demanding uniform beam quality without modulation speed limitation, such as life sciences, digital laser projection, interferometry, laser beam homogenization, lithography, metrology, and fiber-based sensor systems. Compact and plug-and-play, the PFMS is engineered for seamless integration into fiber-coupled assemblies, providing robust despeckling and long-term reliability in demanding environments including space deployment.
