Polarization-Maintaining Fiber Collimator
Feature:
High Power Handling
Low Insertion Loss
High Extinction Ratio
High Return Loss
The Polarization-Maintaining Fiber Collimator converts the polarization-preserving signal from the incident optical fiber into a spatially parallel output beam.
In the interferometric fiber sensor based on optical coherence detection, the use of polarization-maintaining fiber can keep the linear polarization direction unchanged and improve the coherent signal-to-noise ratio to achieve high precision measurement of physical quantities.
Polarizing collimator can be used alone, or with filters, isolators, etc. We can customize various wavelength ranges and various output beam diameter and power requirements of fiber collimator according to customer needs.
Polarization-maintaining devices are the main advantage products of Raysung Photonics。
