Fiber Collimators (Fiber Ports) for producing a collimated beam (low divergence beam) with Gaussian beam profile exiting a single-mode or polarization-maintaining fiber cable, available with different housing types and with smaller or larger focal lengths (also larger housing type). All Fiber Collimators have an adjustable focus and are available for different connector types. Amagnetic Fiber Couplers (made from Titanium) are also available as well a collimators with integrated wave plate.
