The series of fiber couplers are compact, cleverly designed and capable of precise five-dimensional adjustment in very small Spaces. It can be aligned with five degrees of freedom: linear alignment of the lens in X and Y, angular alignment for tip and tilt, and Z adjustment using the tip and tilt controls simultaneously. the travel range of the aspheric lens in the X and Y direction is ±0.5 mm, the angular alignment range is ±4˚, the travel range in the Z direction is more than 2 mm. The couplers also have high coupling efficiency (70%) and good stability (<5%@72h).
◆ Broadband AR coating at 405nm, 532nm, 780nm & 1550nm
◆ Available focal length: 6mm, 15mm，18mm
◆ Fiber interface type: FC/PC, FC/APC, SMA
◆ Exquisite stainless steel case

We will adjust the fiber couplers separately for each storage part, but due to the user's diverse beam conditions, the user needs to adjust again when using it to obtain the best coupling effect. The coupling efficiency and stability of the fiber couplers are closely related to the final state.
