The CPA series of fiber couplers with five degrees of freedom are available with a variety of focal length and coating options. They are designed for compact size and high coupling efficiency with fine adjustment of X, Y, and Z pitch and yaw. Every coupler uses a movable lens as the alignment mechanism while holding the fiber stationary. All lenses are AR-coated. For an ideal Gaussian beam and standard fibers, you can reach coupling efficiencies more than 70%. These fiber couplers are available in non-magnetic stainless steel housings with receptacles for FC/PC or SMA fiber optic connectors.
