SFC/SFS StraightFocus is a series of positioners/scanners with long ranges for microscope objectives. The available displacements are 100 to 800 µm. The specialty of StraightFocus´ is, the guidance, which is optimized regarding straighness of travel. Mounting and exchange is made simple by clamping the unit to the top adapter by a standard screw (Allen-key). StraightFocus´ are available as open-loop, with strain-sensors (SFS) of with capacitive sensors (SFC) – the latter for highest precision.
