Z-Axis Drive and Controller
MFC-2000 - Applied Scientific Instrumentation (ASI)
The MFC-2000 has been specifically designed to provide a high resolution and highly repeatable, means of controlling the focus/Z position of the microscope stage. Precise control of the microscope's focus is obtained through the use of a closed-loop DC servomotor employing high resolution encoders for positioning feedback. By using closed-loop control of the focus position, there is no chance that the focus point can be lost as can occur with open-loop stepper motors.
