• Spot size: 350u-1400u

Polarization-Maintaining Fiber Collimator is assembled precisely by PM fiber pigtail and a Grin lens or C-Lens, which can convert the divergent light into a parallel beam (Gaussian beam) from fiber export , or couple space parallel light into the fiber. It can be used singly to achieve a specified beam size at the required position, or paired with other optical components such as filters and isolators in between two collimators to meet specific customer needs. In fiber optic interferometric sensors based on optical coherence detection, the use of polarization-maintaining fibers can ensure the unchanged polarization direction, improve the coherence signal-to-noise ratio, and achieve high-precision measurement of physical quantities.

When making a polarization maintaining connector, the axis direction of the cat's eye connection is aligned with the connection line direction of the key slot fiber core, also known as slow axis alignment. When the two lines are perpendicular, it is fast axis alignment.
