Project Description
Polarization Maintaining Dual Fiber Collimator
The Dual PM Fiber Collimator is the basic element for in-line PM fiber optics components, such as PM Circulators and PM WDM. It has high extinction ratio, low insertion and high return loss. The unique processing and high quality AR coating also enable this collimator to handle high power.
If you do not see a standard PM Fiber Collimator that meets your needs, we welcome the opportunity to review your desired specification and quote a custom PM Fiber Collimator . Requests for custom fiber pigtails, different wavelengths and handling power of operation or other specific needs will be readily addressed.

- The specifications are w/o connector.
- For devices with connectors, IL will be 0.3dB higher, RL will be 5dB lower and ER will be 2dB lower. The default connector key is aligned to slow axis. Power transmits through the connector less than 2W.
