FOC

The FOC is a nanopositioner dedicated to accurate positioning of microscope objective. It is available with 100, 200, 300 or 500 microns of travel. The FOC is used in a wide range of applications: Z-stack, 3D imaging, autofocus or together with automated focus stabilisation devices, which we can also provide. It is made from aluminium, steel and brass, and is equipped with sensors offering stability in the picometer level.

The brass mounting ring can easily be changed so that every objective would fit in the FOC nanopositioner. Threads available are the RMS, M25, M26, M27 and M32.
