The SMS-120 is a flat-top microscope stage designed for rapid, repeatable positioning of slides, chambered slides, multi-well plates, and other specimen holders. The stage is constructed from machined aluminum plates to minimize distortion. Precision crossroller bearings, high-accuracy lead screws, and stepper-motor based drives, assure smooth, responsive movement over the 120mm travel in the X axis and 85mm travel in the Y axis.

The SMS-120 has robust and innovative design that minimizes maintenance. Great care was made in choosing the right components for maximum lifetime adn repeatability. The X and Y drive systems are fixed in a single position and remain fixed over the entire travel of the stage. (patent panding)

A controller, capable of rack mounting, provides the USB interface between the SMS-120 stage and the computer. USB and virtual com port (VCP) drivers are available for 3rd party software integration. The SMS controller also contains TTL in and out for device synchronization.

Joystick control is provided via a multi-functional inverted joystick. The joystick is height adjustable to optimize comfort during operation. the joystick contains a 6-position speed adjustment know and functional keys. The function keys are positioned on the joystick base and can be located by touch, eliminating the need to look away from the microscope. A centering function moves the stage to the center of travel, the "Home" position advancesthe stage to the end of travel, and a "Work" command returns the stage to a position defined by the user anywhere in the range of travel.

The total travel of the SMS-120 can be limited with adjustable and of travel magnets; a useful tool when working exclusively with specimen holders smaller than a multi-well plate. For users convenience, manual knobs have been provided for fine positioning so that simple manipulations can be made without powering the system.
