• PM Fiber Collimator 1550nm (Working Distance 100mm)

    The polarization maintaining fiber collimator is precisely positioned and packaged with a polarization maintaining fiber pigtail and a focusing lens. It can convert the light output from the fiber into a parallel beam (Gaussian beam), or focus and couple external parallel light into the fiber. It can be used individually to achieve a specified spot size at the required position, or in pairs with optical elements such as filters and isolators placed between the pair of probes to meet the customer's application requirements. In interferometric fiber sensors based on optical coherence detection, the use of polarization maintaining fibers ensures that the linear polarization direction remains unchanged, improving the coherence signal-to-noise ratio, thereby enabling high-precision measurement of physical quantities.

    Beam Waist Spot Diameter: The value is taken at the 1/e² point of the Gaussian beam, with the theoretical value calculated using single-mode fiber for each wavelength.

    Pairing Loss: Refers to the coupling loss between the two fiber collimators in free space.

    Packaging Material, Package Size, and Other Fiber Connector Types: Customizable.
