The 406 High-Performance Large Platform Integrated Two-Axis Linear Stage integrates two orthogonal positioners into a single low profile unit. This stage offers high load capacity in a design based on three parallel plates. Bearing blocks in the top and bottom plates hold pre-loaded linear ball bushings. The inner plate supports pairs of hardened and polished steel rods that ride in the bushings. Backlash is eliminated by spring loading the moving assemblies against the tip of the actuator. The stages may be mounted in any orientation. This stages has a 2.25 in. (57.2 mm) diameter aperture platform and features a convenient array of 1/4-20 tapped holes. Actuators are not included. We recommend our SM-13, DM-13, HR-13, or DM-13L micrometers, our AJS-100-0.5 adjustment screw, and our LTA-HS motorized actuator.
These stages are comprised of two orthogonal, translating supports to provide a low profile for dual-axis translation of the mounting surface. Either a solid or apertured mounting plate is available, and each axis supports either manual or motorized Newport actuators.
A large working area and robust design of three parallel plates provides smooth translation of up to 100 lb. of load, despite the lightweight aluminum construction. Backlash is prevented by as spring loaded actuator assembly. Additionally, these stages can be mounted in any orientation and maintain specifications. The mounting platform features a full array of 1/4-20 or M6 tapped holes. The 2.25 in. (57.2 mm) diameter aperture of Model 406 closes to a minimum of 1.875 in. (47.6 mm) at the maximum diagonal displacement of the stage.
The stages are sold without actuators to allow the comprehensive selection of manual or motorized actuators to choose from. The video shows quick and easy actuator changes on any axis, at any time.
Pre-loaded, stainless steel ball-bearings provide smooth travel for the high load capacity of these stages over each axis over 0.5 in. with <200 µrad deviation.
