670nm Polarization Maintaining C-Lens Fiber Collimator
The 670nm Polarization Maintaining C-Lens Fiber Collimator is designed to convert divergent light from a polarization maintaining fiber into a stable, well-collimated beam while preserving the input polarization state. By integrating precision-aligned PM fiber with a high-quality C-lens, it achieves low insertion loss (≤1.0 dB), high return loss (≥50 dB), and reliable polarization extinction ratio (≥20 dB) at 670 nm.
Optimized for visible red wavelength applications, this collimator provides consistent beam quality and stable polarization performance. Its compact structure and precise alignment ensure reliable operation in scientific and laboratory environments where accurate polarization control and beam delivery are required.
