High Precision and Lockable Manual Fiber Polarization Rotator/Controller

SKU: POCM

The POCM Manual Mini Polarization Controller features a novel design that combines high precision, compact size, low loss, high extinction, and reliable lockability. Unlike traditional fiber strain-based controllers, the POCM utilizes three rotatable waveplates positioned between collimators, enabling precise and repeatable access to all possible polarization states. Key features include: Rotatable waveplates controlled via finger or screwdriver adjustment; Magnetic locking mechanism to secure polarization settings without drift, maintaining stability for years; and Superior to conventional strain-based controllers, which degrade over time.
Polarization Control Configuration:
●   First Half-Wave Plate: Adjusts the initial polarization angle.
●   Quarter-Wave Plate: Converts linearly polarized light to elliptical or circular polarization.
●   Second Half-Wave Plate: Fine-tunes the polarization angle to achieve the desired output state.
An optional configuration includes rotatable polarizers to ensure the output is strictly linearly polarized. For enhanced polarization purity, a dual-stage configuration is available, with the output provided through a PM fiber aligned to the slow axis. The POCM is specifically designed for integration into modules or systems with limited space while offering robust performance and long-term reliability.
