Direct Drive Linear Translation Stage of series 8MTL220 are based on 3 phase ironless linear brushless servo motor technology. Direct drive technology allow user to reach zero backlash motion with high accuracy, repeatability and low friction.
Linear non-contact optical encoder as a feedback system guarantees direct control of position with sub-nanometer resolution of motion.
Naturally aged aluminum alloy guaranties high temperature stability, softness of 8MTL220 instruments and excellent long period kinematics without drift of guide system. Small Special guiding system with caged recirculating ball ensure long last precision of stage.
Translation stages of series 8MTL220 can be prepared for clean rooms and vacuum up to 10-3 Torr with small changes. For higher vacuum please contact Standa support. Additional requirement of cleanliness could be requested separately.
Motorized translation stage can be easily connected to standard imperial/metric optical table directly. XY scanning stages can be directly assembled without using any connecting plates. For extreme orthogonality please contact Standa separately.
Motion control of 8MTL220 series translation stages is available with Standa or ACS motion Controllers & Drivers in exposed or housed configurations.
For industry applications 8MTL220 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.
