561 and 562 Series ULTRAlign Linear Stages feature stainless steel construction for superior long-term stability, with thermally matched, hardened steel crossed-roller bearings for unsurpassed performance. The crossed-roller bearings and precision-manufactured bearing reference surfaces provide exceptionally linear travel, with angular deviation better than 100 µrad about any axis. We measure each stage on a six-axis interferometer to ensure performance.
561/562 Series Stages are ultra-high performance positioners. They were originally designed for precision fiber optic alignment, one of the most demanding precision positioning applications. Today, they are finding increasing applications in other fields as well.
The robust design of the 562 Series Stages makes them ideally suited for repetitive, high-use industrial manufacturing and research applications. These stages have greater thermal immunity due to their higher mass. And larger diameter bearings increase the stiffness of the stage. Oversized loads and complicated platform configurations can easily be accommodated, since all actuators are located below the top surface level.
Each 561/562 stage axis is equipped with a non-influencing locking mechanism to maintain sub-micron positioning when locking or unlocking. Specially designed actuator mounting blocks allow quick and easy actuator changes, on any axis, at any time. Both right- and left-handed stages are available for ergonomic actuator placement. And a choice of manual, motorized, or electrostrictive actuators will meet every positioning need.
