Micromanipulators of the SM series are equipped with a stepper motor driving mechanism, which, in combination with the control devices Tango and MCL, enables even smallest step sizes up to 0.01 µ m. Only these extremely small single steps enable stepper motors to carry out a motion sequence that is absolutely free of vibration.

The mechanical construction of the micromanipulator SM 3.25 is exceptionally compact, so that it can be attached directly to the plain stage of a microscope.
