MA42

For supplementary motorization of the Z-axis the focus drive MA 42 is installed by removing the fine focus knob from the microscope and fixing the MA 42, in conjunction with a special coupling, directly to the shaft of the fine focus. This method prevents any slippage, or loss of steps. Where this is not possible - due to the design of the microscope - the drive ensues via a friction pulley, positioned on the fine focus knob.
