High Precision Polarization Maintaining Fiber Collimator (PM Fiber Collimator)
GRACYFIBER's polarization-maintaining fiber collimator (PM Collimator) is a high-precision micro-optical component designed for extremely stable polarization state transmission and efficient free-space beam projection. Whether used in telecommunications networks, quantum optics, or industrial laser and sensing systems, this collimator delivers superior optical performance across a wide spectral range of 780–1550 nm. Available in 1-channel or 2-channel configurations, combined with rigorous polarization axis alignment and extremely low optical loss, it serves as the most reliable physical layer bridge between confined light waves within optical fibers and free-space detection systems.

Remark:
* Above specifications are for devices without the connectors.
* For devices with connectors, IL will be 0.3dB higher, RL will be 5dB lower, and ER will be 2dB lower.
* The PM fiber and the connector key are aligned to the slow axis. fast axis is blocked.
Solved Pain Points/Value: Typical polarization extinction ratio (ER) reaches up to 25 dB in the 1310/1480/1550 nm and 980/1064 nm bands. Simultaneously, the typical insertion loss in the 1310/1480/1550 nm band is only 0.3 dB (Note: Insertion loss increases by 0.3 dB with connectors, reducing ER by 2 dB). This ensures that polarization-sensitive systems (such as interferometers or coherent communication systems) maintain absolute signal purity and strong optical power when projecting beams into space.
Comprehensive coverage of center wavelengths of 780/850 nm, 980/1064 nm, and 1310/1480/1550 nm, with a precisely customizable working distance ranging from 5 to 100 mm. Combined with extremely small beam diameter control of 600 μm, it perfectly adapts to complex optical path requirements ranging from close-range biomedical imaging to long-range LiDAR sensing.
Pain Points Solved/Value Boost: In the manufacturing process, both the polarization-maintaining fiber and the connector key are strictly aligned with the slow axis, while the fast axis is blocked. This industrial-grade single-axis alignment design significantly reduces the debugging difficulty for OEMs during system integration and prevents system errors caused by polarization rotation.
Pain Points Solved/Value Boost: Capable of handling high continuous input optical power up to 0.5 W or even 1 W, while providing extremely high return loss of at least 50 dB. Supports stable operation over a wide temperature range of -5°C to 65°C (storage temperature range of -40°C to 85°C), easily handling the high heat generated by high-power laser pumped systems and harsh industrial measurement environments.
