Focus Drive with Integrated Controller
Focus Drive with Integrated Controller is a microscope attachment for compound and stereo microscopes that provides high resolution movement of fine focus and at the same time retains manual movement of fine and coarse focus. The Focus Drive with Integrated Controller consists of a step motor connected directly to the fine focus shaft of the microscope via a flexible coupling, of a motor controller that drives the motor, and of an adapter that fits over the coarse focus knob of the microscope. The use of a high torsion stiffness flexible coupling ensures virtually no backlash in the drive while allowing easy installation by the end user. This Focus Drive does not need any additional control units; it connects directly to the computer serial port via a cable with built-in converter. This innovative design provides cost saving, requires less desk space, and reduces cable clutter. See possiblesystem configurations. The focus drive can be ordered with digital output.
