Overview of the A-361 Nanopositioning Stage
Introducing the A-361, a cutting-edge air-bearing XY-rotation stage developed by PI (Physik Instrumente). This innovative single-module platform is designed to deliver exceptional precision and reliability in various demanding applications across research and industry.
Compact Design and Specifications
The A-361 stage stands out with its remarkable low profile of only 39.5mm tall and a substantial 200mm diameter motion platform, optimizing workspace in tight environments. It offers a translational motion of 5mm in both the X and Y axes, paired with a rotational motion around the Z axis measuring 2°.
High Precision and Performance
Equipped with outstanding performance specifications, the A-361 is suitable for the most rigorous environments. It features a minimum incremental motion of less than 30nm for linear movements and sub-0.5µrad for rotation. The calibrated positioning accuracy impressively reaches ±0.2µm in XY and ±5µrad in ?Z. Additionally, the bidirectional repeatability achieves a remarkable 0.2µm in XY and 4µrad rotationally.
Applications in Various Sectors
A versatile tool, the A-361 PIglide XY-theta stage excels in several applications, including wafer inspection, flat-panel display metrology, fiber and optics alignment, maskless lithography, and µLED manufacturing. Its clean design and impressive stability make it an ideal choice for semiconductor and photonics production environments.
Technological Innovations
A remarkable aspect of the A-361 is its frictionless bearing design combined with a lock-down mechanism, providing ultra-high stability. The integration of air bearings and non-contact motors prevents wear, allowing for a maintenance-free operation that can last decades. The position-locking feature further enhances stability, especially in critical measurement and alignment tasks, while a built-in vacuum chuck is perfect for handling delicate substrates in the semiconductor and optics markets.
Direct Drive Mechanism
The A-361 employs voice-coil direct drives, delivering frictionless and responsive motion capabilities. With the ability to generate up to 6N of continuous force and a peak of 19.2N, it can support payloads reaching 3kg, all while maintaining a lightweight construction using hard-anodized aluminum for added durability and stability.
Integration and Operation
Designed specifically for cleanroom conditions, the A-361 requires only dry, oil-free compressed air that adheres to ISO 8573-1 purity standards. Its air consumption is an efficient 28L/min, promoting effective continuous operation. When combined with the A-523 Z Tip/Tilt Stage, it creates a robust array for six-degree-of-freedom nanopositioning, providing complete spatial control for high-precision alignment tasks in photonics, optics, and micro-assembly. PI also offers a range of integrated accessories such as air-preparation kits, multi-axis controllers, and custom cabling solutions for seamless system integration and enhanced performance.
