Miniature Linear Stage

Miniature Linear Stage - MMG ™

The DOVER MMG ™ Series Miniature Linear Stage has an option for a 25mm travel linear voice coil actuator. Our stage is also available with 3 phase servo motors in travels from 25mm up to 150 mm. Our miniature linear stage delivers nearly twice the accuracy at virtually the same cost as competitive standard-grade options. Short lead times facilitate reduced time to market for equipment manufacturers or provide greater machine uptime for end users in production environments.

    • Stackable as XY or XYZ translation stages
    • Ideal for high speed step and settle or constant velocity applications
    • Available with integral counterbalance for vertical applications
    • Anti-creep crossed roller ways standard
    • Adjustable end of travel limits
    • Available in either steel or aluminum

Application Focus

For High Throughput Imaging applications, the MMG ™ Miniature Linear Stage delivers excellent mechanical and servo stiffness to optimize motion for:

    • Sample / part positioning: Sustained throughput of up to 2000 moves per minute are possible.
    • Focal Plane Definition: Z objective positioning moves (<5um) are often accomplished in <20ms, in parallel with XY stepping.
    • Frame Capture: In-position stability is key to producing quality images. Position stability / jitter is typically less than 100nm.
    • Space savings: Miniature linear stage designed to fit inside benchtop instruments
