fiber positioning system

FAPOS 3D fiber alignment system
  • 3D system for fiber positioning / coupling
  • compact size, easy to use
  • mechanical linear motion in xyz direction up to 5 mm
  • optional 3D piezoelectric motion for the highest resolution
  • accessories (fiber holder, micro objective mount, fiber rotator)

The series FAPOS was especially developed for precision positioning of optical components, e.g. fiber coupling/alignment problems. Compact size and a modular design allow flexible and universal applications.
Side A can be adjusted using micrometer drives for mechanical motion in x-, y- and z-direction.
Side B can be equipped with a TRITOR element for finest piezoelectric motion up to 100 µm. Please see table below with configuration examples.
Several accessories such as fiber holders or holders for microobjectives are available and can be mounted on the top plate on both sides. The FAPOS should be the first choise for cost sensitive developement in R&D projects.
