Polarization-Maintaining Fiber Collimator 780nm (Working Distance 100mm)

It is composed of polarization-maintaining fiber pigtail and focusing lens with precise positioning and packaging, which can transform the outgoing light of fiber transmission into parallel beam (Gaussian beam), or focus and couple the parallel light from the outside into the fiber. It can be used alone to achieve the specified size spot at the required position; it can also be used in pairs, adding filters, isolators and other optical components between a pair of probes to achieve the purpose of customer use. In the interferometric fiber sensor based on optical coherence detection, the use of polarization-maintaining fiber can ensure that the linear polarization direction remains unchanged, improve the coherent signal-to-noise ratio, and achieve high-precision measurement of physical quantities.

General Parameters

When making a polarization-maintaining device connector, the cat's eye connection axis direction is perpendicular to the keyway direction, also known as slow axis alignment, and vice versa is fast axis alignment. As shown in the figure:
