The PM Fiber Collimator is the basic element for in-line PM fiber optics components, such as PM isolator and PM DWDM. It has high extinction ratio, low insertion and high return loss.
The PM Fiber Collimator is the basic element for in-line PM fiber optics components, such as PM isolator and PM DWDM. 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.
DK Photonics offers a large selection of polarization insensitive or polarization maintaining PM Fiber Collimator. These devices can handle powers rang from 300mW to 20W or other on request, and have center operating wavelengths ranging from 850 nm to 1650nm.
If you do not see a standard isolator 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.
