1550nm Single Mode C-Lens Fiber Collimator
The 1550nm Single Mode C-Lens Fiber Collimator is designed for efficient beam collimation in fiber optic systems operating in the C-band. Utilizing precision-aligned C-lens technology, this device delivers a stable and low-divergence output beam with high coupling efficiency and minimal insertion loss.
Optimized for SMF-28e fiber, it ensures excellent optical performance with low polarization-dependent loss and high return loss. The compact package and robust structure make it suitable for integration into optical communication systems, laser modules, and fiber optic sensing applications.
