1550nm Polarization Maintaining C-Lens Fiber Collimator
The 1550nm Polarization Maintaining C-Lens Fiber Collimator is designed to deliver a highly collimated output beam while preserving the polarization state of the input signal. By combining precision-aligned PM fiber with a high-quality C-lens, this collimator ensures excellent beam quality, low insertion loss, and stable polarization performance at 1550 nm wavelength.
Optimized for long-wavelength optical systems, it offers low back reflection (≥50 dB) and high polarization extinction ratio (≥20 dB), making it ideal for applications requiring high coherence and polarization stability. With compact packaging and robust construction, it provides reliable operation in both laboratory and industrial environments.

FAQ
- Q: What is the difference between a PM collimator and a standard single mode collimator?
- A: A polarization maintaining (PM) collimator preserves the polarization state of the input light, while a standard single mode collimator does not control polarization. PM collimators are designed using polarization maintaining fiber and precise axis alignment, making them suitable for applications requiring stable polarization, such as interferometry and coherent systems.
Questions & Answers
How do I choose the correct working distance?
The appropriate working distance depends on your specific application requirements. A shorter working distance, such as 5 mm, is suitable for compact systems and short-distance coupling where space is limited. A 50 mm working distance is the most commonly used option, offering a good balance between beam size and alignment tolerance for general laboratory applications. For applications requiring longer beam propagation or greater separation between components, a 100 mm working distance is recommended. If you are unsure, 50 mm is typically considered a standard and versatile choice.
