Aerotech ANT130-5-V Vertical Lift Stage

Aerotech’s ANT130-5-V is a linear-motor-driven wedge-style vertical lift stage that provides the exceptional resolution, accuracy, and in-position stability required in nanopositioning applications, all while offering travel up to 5 mm. It is a precision stage that is perfectly at home in industrial applications. The ANT130-5-V was designed for stand-alone use or can be seamlessly integrated with other stages in the Aerotech ANT stage family for a superior multi-axis nanopositioning system.

ANT130-5-V stages utilize advanced direct-drive technology, pioneered by Aerotech, as well as anti-creep crossed-roller bearings to achieve the highest level of positioning performance. Aerotech direct-drive technology is non-cogging, noncontact, high-speed, high-resolution, and high-accuracy. The lack of hysteresis or backlash enables accurate and repeatable nanometer motion. The unique drive and bearing combination, packaged in an extremely compact profile and footprint, offers tangible advantages in high-precision positioning applications such as disk-drive fabrication, fiber alignment, optical delay element actuation, sensor testing, and scanning processes that demand smooth, precise, stable, and repeatable motion.

The ANT130-5-V family has universal mounting and tabletop patterns that allow for easy system integration. Two, three, or more axes can be easily combined for flexible system designs and multi-axis configurations.

Outstanding accuracy, position repeatability, and in-position stability require high system resolution. The ANT130-5-V stage’s industry-leading 2 nm minimum incremental step size provides this high level of performance.

New URS precision rotation stages from Newport

Newport Corporation (www.newport.com), a global leader in photonic and laser solutions that “Make, Manage and Measure Light”, is proud to announce the release of the URS50BPP and the URS50BCC precision rotation stages that feature 360°, continuous motion. These new stages have the smallest footprint of 50mm in size, and are offered in very affordable price, while maintaining the high performance of URS motion product family from Newport.

The URS50BPP and the URS50BCC provide very low wobble and backlash-free, continuous rotation with extremely high MTBF of up to 20,000. Competitively priced, the high-performing rotation stages feature large stage performance in a very small package. The two stages also offer exceptional 6µm eccentricity and easy integration.

The URS50B’s feature a one of a kind, two-part bearing design with pre-tempered bearings and steel gears to ensure long-life motion positioning and precision. The URS50BCC, the DC-motor version with embedded index pulse for precision homing, is best suited for demanding applications that need bi-directional positioning.

The economical URSBPP stepper motor version is ideal for less demanding, yet precision rotation applications. Each URS50B has a cable URS50B for plug-and-play compatibility with XPS, SMC and ESP.

Aerotech introduces brushless linear servomotor-driven stages for industrial applications

Aerotech (www.aerotech.com) has unveiled a new PRO-LM range of direct-drive, brushless linear servomotor-driven stages. The range now includes a new 280mm wide version that comes in eight travel options from 300mm to 1.5m for heavy-load precision positioning and high-throughput applications in harsh environments. The fully protected and side-sealed/hard-top stages have heavy-duty linear motion guide bearings, optional cable management and sub-micron encoder feedback. These are available in nominal widths of 165mm, 225mm and 280mm, which can be mixed to optimize application load and travel requirements.

The new PRO280LM is based on the successful side-sealed design that the company has developed over the past generations of ball screw-driven stages and linear motor. The aluminum hard top cover – finished in a scratch-resistant hard coat – is a preferred alternative to plastic bellows or soft fabric stage covers, especially made for applications like laser machining. Its vertical-tensioned side straps completely seal the internal stage components from process or machining debris. A wide array of optional tabletops with steel inserts permit YZ, XZ or XY configurations with other PRO series stages with 5arc-sec orthogonality certification. Tabletop plates are available for Aerotech’s AGR, ADRT and ADRS series rotary stages or to suit customer workpiece mounting in inch and metric hole patterns. Cable management is also available for single-axis or customer-specified XYZ+rotary, XY, and XYZ stage configurations.

Aerotech said that its new PRO280LM features a positioning resolution of 250nm from a choice of amplified sine output encoders or 0.1 micron line driver. Additional impressive specifications include accuracy to +/-3 microns for the 1.5m travel version (+/-2 microns for the 300mm travel stage) with speeds to 2m/s and acceleration to 3g.
