1550nm Polarization Maintaining Dual Fiber Collimator C/G Lens with PM Optic Fiber
Polarization-maintaining dual-fiber collimator is a dual-fiber collimator made of polarization-maintaining dual fibers. A dual-fiber collimator is a device that collimates the light coming out of the dual fiber or injects the collimated light into the dual fiber. Fiber collimator is an optical element used for input and output in dual-fiber communication optical devices. Its main function is to couple light into the required device with high efficiency. It can also be combined with other optical devices to achieve many other uses.
