The stepper motor driven focus unit fits over the coarse control knob of the microscope using an adaptor. This allows full manual movement of the coarse control while maintaining high resolution on the motor driven fine focus. The resolution is 0.025 to 0.1 micronsdepending on the microscope. Power for the focus motor is provided by a 15 way connector on the H100 series stage.

Yes! I would like to request some more information on the Prior H120 focus unit.
