Features
Single Rail Linear Stage Applications
The VP-25AA's actuator top rail can be used as a single-rail linear stage to position small and light weight parts with the optional 561-RAIL rails. It can be used to position optical fibers, micro-optics, sensors, or other small and lightweight parts. For added versatility, a mounting interface for a dovetail rail compatible with the popular ULTRAlign™ positioning system is provided. This system offers a wide selection of interchangeable mounts for optical fibers, fiber arrays, objectives, or GRIN lenses in a variety of fiber alignment applications.
Non-rotating tip
The non-rotating tip is essential to eliminate undesirable periodic motion variations caused by the variable contact made between the actuator tip and the mating surface.
Integrated Linear Encoder
The VP-25AA is based on the same innovative design used in the VP-25XA linear stages and features a high-resolution linear scale encoder for exceptional repeatability and accuracy. The scale is fixed on a moving rail to which the actuator’s tip is permanently attached without any contact to the mounting shaft. This concept eliminates all drivetrain induced motion errors and minimizes hysteresis between the scale and the actuator tip.
