FOCHS.100

The FOCHS.100 is a tubular design piezotage dedicated to microscope objective high speed nanopositioning. It is offered with 100 microns of travel. The FOCHS.100 is used in a wide range of applications : Z-stack, laser machining, autofocusing. It can work also together with automated focus stabilisation devices (for example, CRISP from ASI Imaging). It is made from aluminium, steel and brass. It is equipped with sensor offering stability in the picometer level.

The brass mounting ring can be easily exchanged so that almost any objectives can be used with the FOCHS.100 nanopositioner. The threads which are available are : RMS, M25, M26, M27 and M32.
