Delay Line Stage and Controller, 225 mm Travel

The DL225 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 225 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.
