The VP-25AA actuators combine precise positioning with highly reliable performance. It is based on the same innovative design used in the VP-25XA linear stages and features a high-resolution linear scale 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. The non-rotating tip is essential to avoid undesirable periodic motion variations caused by the variable contact between the actuator tip and the mating surface.The top rail of the VP-25AA can also be used as a single-rail linear stage 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.

VP-25AA执行机构定位精确，性能可靠。它基于VP-25XA线性阶段相同的创新设计，具有高分辨率线性刻度，具有卓越的重复性和准确性。该秤固定在一个移动的轨道上，执行机构的尖端永久地附着在该轨道上，而不与安装轴有任何接触。这一概念消除了所有传动系诱导的运动误差，并最小化了尺度和执行机构顶端之间的滞后。非旋转的叶尖是必不可少的，以避免不必要的周期性运动变化引起的变动接触之间的执行机构的叶尖和配合面。VP-25AA的顶轨也可以作为单轨线性级，用于定位光纤、微光、传感器或其他小而轻的部件。为了增加通用性,燕尾导轨的安装接口兼容流行ULTRAlign™定位系统。该系统为光纤、光纤阵列、目标或GRIN透镜在各种光纤对准应用程序中提供了多种可互换的支架。
