Model 9091 Five-Axis Fiber AlignerIdeal for single-mode-fiber applications, the 9091 five-axis fiber positioner has all motions independently and firmly connected to a single base, giving you incredible 0.02-µm resolution coupled with unparalleled stability. Fast alignment is enabled by separate coarse and fine x and y adjustment screws. An 8-32 (M4) mounting hole allows placement on any post or pedestal in your lab. The 9131 Fiber Coupling Kits include the 9010 fiber positioner as well as the required accessories for fiber launch applications: 9092 coupler body, 9123 objective body, 9126 ST adaptor and 9127 FC adaptor.
Model 9091 Five-Axis Fiber Aligner
With this aligner, the X and Y positions are actuated by side-mounted screws. An extra pair of X–Y adjustments provides fine resolution by turning the coarse-adjustment screws via a cam.
The fiber end is mounted at the fourth corner of a square formed with three adjustment screws. Turning all three screws the same amount results in pure translation in the Z direction. Turning two adjacent screws provides pure tilt.
To simplify tilt and Z motion in this fiber positioner, we added a knob to the center screw (see figure). This knob is attached to a planetary gear that couples the motion of the three screws. Turning the knob turns all three screws simultaneously, giving you Z translation. Keeping one of the two outer screws stationary (with an Allen-key) while turning the knob causes the two remaining screws to turn and tilt the fiber end.
