Description
LFIBER's polarization maintaining (PM) fiber optical collimator (450nm 460nm 630nm 632nm 650nm 780nm 850nm 980nm 1064nm 1310nm 1550nm 2000nm) is used to launch a beam of light from an optical fiber into free space and then to capture that light and refocus it into the same or another fiber. By using Panda polarization maintaining fiber (PMF), the PM fiber collimator can maintain a well-defined state of polarization (SOP) of the light signals. They meet most demands with good performance over a wide temperature range. LFIBER’s PM fiber optical collimators feature epoxy-free in the light path, low loss, high extinction ratio, high reliability qualification complying with GR-1221-Core standard.
Note:
1. For polarization maintaining (PM) fiber collimator with connector, IL is 0.3 dB higher, RL is 5.0 dB lower, and ER
will be 2.0 dB lower.
2. Insertion loss is measured through a PM optical collimator pair.
3. Unless otherwise specified, the slow axis of the PM fiber is aligned with the key of the connector.
4. Please specify the operating wavelength, working distance, extinction ratio requirements, housing type (package
dimensions), fiber length, connector type, etc. in the orders. (See the ordering information section.)
5. This PM fiber collimator is customizable, and the above specifications are subject to change without notice.
