Ball Screw Based Linear Translation Stages of series 8MT165 are based on 3 phase ironless linear brushless servo motor technology (version with stepper motor available by request) . BLDC technology allow user to reach motion with high accuracy, repeatability and low wear.

Rotary non-contact optical encoder as a feedback system guarantees in-direct control of position with sub-nanometer resolution of motion.

Naturally aged aluminum alloy guaranties high temperature stability, softness of 8MTL165 instruments and excellent long period kinematics without drift of guide system. Special guiding system with recirculating balls ensures long-lasting linear positioner precision.

Linear translation stages of series 8MTL165 can be prepared for clean rooms and vacuum up to 10-3 Torr. For higher vacuum please contact Standa. Higher cleanliness requirements could be requested additionally.

Motorized translation stage can be easily connected to standard imperial/metric optical table directly. XY configuration stages can be assembled by direct stacking without using any connecting plates. Standa could deliver assembled preset XY system with extremely high orthogonality for additional cost.

Motion control of 8MT165 series translation stages is available with Standa or ACS motion Controllers & Drivers in exposed or housed configurations.

For industrial applications 8MT165 stages can be supplied mounted on standard optical table or extremely flat granite plate fully sealed from spray and dust to ensure performance of kinematic pairs

1) CPR - encoder periods or counts per revolution; with default x4 evaluation PPR - pulses per revolution.

2) Absolute Accuracy & Bi-Directional Repeatability measurements are processed with Zygo ZMI 501 Michelson laser interferometer.

3) Pitch & Yaw measurements are processed with 11D-ALI-COL electronic autocollimator. Resolution of 11D-ALI-COL: 1 µrad. Environment error: 1 µrad.

4) Maximum Velocity is electrically limited by encoder and driver CUT-OF frequency; maximum velocity is also limited by guiding system.

5) Maximum Acceleration is limited by Drivers` Peak Current, Motors` Peak Current and External Load (inertia). Please contact Standa for support.

6) Load Capacity is limited by position of load and integrated guiding system. Please contact Standa support for loading calculation.

7) Moving Mass is constant parameter of system which characterize m0 or inertia of unloaded system.

8) Recommended controllers & Recommended drivers can be optimized for a certain application. Please contact Standa support for recommendation.

9) Recommended power supply depends on required duty cycle and load. Please contact Standa support for recommendation.

10) Differential Outputs are available in passive (buffered) or active (modulated) way with LCMv2.

11) Stages can be assembled with better orthogonality by request.

12) Scalar Control can be implemented with USB / TCP-IP / RS-232 communication iterface; for vector control we recommend to use EtherCAT.

13) Stages include special covers which allow their usage in dusty and partially wet environment
