FOC

 The FOC are nanopositioners dedicated to microscope objective accurate positioning. They are offered with 100, 200 or 300 microns of travel. The FOC is used in a wide range of applications : Z-stack, automated focus or together with automated thermal expansion compensation (for example CRISP from ASI Imaging). It is made from aluminium and brass, and is equipped with sensor offering stability in the picometer level.

The brass mounting ring can be easily exchanged so that any objective can be used with the FOC nanopositioner. The threads which are available are : RMS, M25, M26, M27 and M32.
