The VP-25X stages address multi-axis, high precision positioning requirements in fiber optics, bio-medical, semiconductor, and test and measurement applications. Features including its ultra-compact size and high reliability make the VP-25X stages appropriate for device testing, micro-assembly, micro-machining, and manipulation of small, lightweight parts such as fiber optical devices, micro-optics, MEMS, cell probes, or semiconductor devices.
Based on a high precision low-friction ball screw and re-circulating ball bearings, the VP-25X stages deliver highly reliable positioning performance at a maximum speed of 25 mm/s. Compared to alternative direct-drive technologies, the ball screw drive provides greater thrust for higher load capacity, higher efficiency resulting in less heat induced position drift and minimum tuning efforts. Furthermore, the self-locking feature at power-off considerably enhances operational safety.
The modular VP-25XA stages enables the assembly of compact multi-axes positioning systems. For example, combining three VP-25XA stages and a VP-BK bracket produces a versatile and compact 3 axis motion system, while maintaining the height of the horizontal mounting surface to as low as 4 in. (±0.5 in.). For applications requiring up to 6 axis of motion, the SR50 and PR50 rotation stages and GON series goniometers (see Anti-Backlash Goniometric Rotation Stages) can be easily added to the system. This complete modular approach provides the greatest flexibility and customization, while taking advantage of high precision performance and ease-of-use.
The VP-25X stages are available in two versions: The VP-25XA provides a RS422 standard encoder output with 0.1 µm resolution, that is compatible with our popular ESP300 and other motion controllers. The VP-25XL provides a 1 Vpp analog encoder interface compatible with our XPS motion controller. These stages deliver a reliable 10 nm motion sensitivity, and better than 140 nm bi-directional repeatability.
Need Accuracy to 1 µm?
For critical positioning applications, Newport offers micropositioning calibration services. We will create, implement and verify an electronic compensation process to improve the absolute position accuracy of your Newport VP-25XL Series stages when commanded by our XPS advanced motion control system. Compensation is performed at 20.0 °C, +/-0.2 °C, for linear and non-linear errors, ensuring accuracy of up to 1 µm/100 mm over center 80% of travel. A certificate of calibration per Newport Metrology Procedure A167 and measured error maps are provided. Click here for complete information.
