The fiber positioning system FAPOS series was especially developed for precise 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-directions.

Side B can be equipped with a TRITOR element for the finest piezoelectric motion of up to 100 µm. Please see table below for configuration examples.

Several accessories, such as fiber holders or holders for micro objectives, are available and can be mounted on the top plate on both sides.
The fiber alignment system FAPOS should be the first choice for cost sensitive development in R&D projects.
