The DL325 Delay Line Stage utilizes FEM-optimized extruded aluminum body to avoid bending effects or deflection under load. The recirculating ball bearing slides provide excellent payload capabilities, long life, smooth and low noise motion over 325 mm.

Unlike screw driven stages, the DL’s  employ centered, high efficiency 3-phase, synchronous ironless linear motor as the driving element. Such  drive system is absolutely non-contact and has the advantage of higher speed, high acceleration and high system responsiveness, as well as no wear associated with motor brushes or drive screws. Because of the fully integrated linear motor, the DL series stages are  shorter than a comparable screw driven stage.

Precision position feedback is provided by a very repeatable linear scale with  encoder signals being  interpolated to nanometer resolution by Newport motion controller, providing  outstanding position sensitivity, repeatability, and stability.  To avoid additional electronics or mechanics use and improve reliability and accuracy, home position is incorporated on the same scale. Thus, the DL series stages are  the optimum solution for space constrained applications that require high-throughput, high reliability, and ultra-quiet operation.

Single pass delay of 2.2 ns with MIM of 0.5 fs

DL325延迟线级采用经feme优化的挤压铝型材，避免了负载下的弯曲或偏转。滚珠轴承滑块具有优良的载荷能力，使用寿命长，运动平稳，噪音小，超过325毫米。

与螺杆驱动不同，DL采用了中心、高效的三相同步无铁直线电机作为驱动元件。这种传动系统是绝对非接触的，具有转速高、加速度大、系统响应速度快、电机刷或传动螺丝不磨损等优点。由于采用全集成直线电机，DL系列级比同类的螺杆驱动级短。

精确的位置反馈是由一个非常可重复的线性比例提供的，编码器信号被插值到纳米分辨率的新港运动控制器，提供卓越的位置灵敏度，重复性，和稳定性。为了避免额外的电子或机械使用，并提高可靠性和准确性，家庭位置被纳入相同的规模。因此，DL系列级是空间受限应用程序的最佳解决方案，这些应用程序需要高吞吐量、高可靠性和超安静的操作。
