Product overview
The F-836 3D alignment system consists of stacked linear stages from the L-836 series. High-resolution stepper motors, high-precision crossed roller bearings, and precision linear encoders make the L-836 linear stages ideal for applications that require a high resolution, high repeatability, and high velocity in conjunction with compact dimensions.
The F-836 XYZ system offers 3 or 6 linear degrees of freedom for 3D alignment. The scalability of the system towards further degrees of freedom is ensured by the future option of integrating goniometers.
Controller and FMPA routines
The alignment system is supplied complete with a preconfigured ACS controller that controls all axes both in the single-sided and double-sided configurations. FMPA routines with a rapid area scan and gradient search have been implemented in the controller (ACS buffer).
Application fields
Applications for 3D alignment over a large travel range by maximizing an analog signal (short and longer travel ranges available). Applications with only one input channel and one output channel, i.e., for the alignment of single optical fibers.

Note on scanning times: values determined using SMF-28 lensed fiber with 15 µm MFD (mode field diameter). Velocity: 2 mm/s, line spacing of the spiral: 0.01 mm
Note on signal optimization: average value based on randomized starting position. Determined using SMF-28 lensed fiber with 15 µm MFD. Frequency: 10 Hz, with optimized parameter set
Unless stated otherwise, the values apply to F-836 XYZ assemblies.
At PI, technical data is specified at 22 ±3 °C. Unless otherwise stated, the values are for unloaded conditions. Some properties are interdependent. The designation "typ." indicates a statistical average for a property; it does not indicate a guaranteed value for every product supplied. During the final inspection of a product, only selected properties are analyzed, not all. Please note that some product characteristics may deteriorate with increasing operating time.
