From the Marzhauser web site here is the description:  The SCAN series has been developed especially for applications in upright microscopes that require automatic and very exact positioning of samples. Enhanced by special adaptations, these microscope stages are perfectly in line with nearly all current microscopes.

With ranges of travel from 75 x 50 mm up to 600 x 600 mm these systems can also reliably carry out high-precision positioning performances in application areas beyond microscopy.

A special long-term lubrication system guarantees that specifications are maintained, even after a very long running period.

Specifically this stage is the model number 00-24-507-0000

• 4 mm lead screw pitch
• Travel Range: max 225 x 75 mm
• Repeatability: < 1µm
• Accuracy:  +/- 4µm
• Orthogonality:  <40 sec., typically < 25 sec.
• Resolution: 0.5µm (smallest step size)
• Max. Travel Speed: 240mm/x, with 4mm lead screw pitch
• Motor: 2-phase stepper motor
• Material: aluminum
• Limit switches: mechanical limit switches
• Weight: 4.800 g
• Surface:  anodic coating, black

Included is the stage insert for 8 slides part number 00-24-505-1100. This stage can be used on any of the Olympus BX series of microscopes.
The controller and joystick are manufactured by the German Company ITK.
