Z positioning of objectives with PIFOC
A positioning of the sample in the Z direction, i.e. along the optical axis of the objective, is required in many examinations or for microscopy technologies. Alternatively, it is possible to move the objective itself in the Z direction. For this purpose, PI offers solutions named PIFOC.

Integrated weight force compensation
The product is equipped with a magnetic weight force compensation. This maintains the position of a load of up to 1 kg aligned vertically to the motion axis even if no power is applied. The weight force compensation can be adjusted by the user.

PIMag® voice coil motor
Voice coil motors are direct drives. In direct drives, the force of the drive element is transmitted directly to the load to be moved without the use of mechanical transmission elements such as coupling, drive screw, or gearhead. Voice coil drives consist of a permanent magnet and a winding body that are located in the air gap of the magnetic field. When current flows through the winding body, it moves in the magnetic field of the permanent magnet. Thanks to their low weight and friction-free drive principle, voice coil drives are particularly suitable for applications that require high dynamics and high velocities at limited travel ranges.
