The new L-505 linear translation stage family from PI (Physik Instrumente) is available with integrated linear encoders providing 0.05 microns and 0.005 microns resolution, respectively. The new design allows for compact multi-axis assemblies, at affordable prices. Many motor and drive variations are available, from fast dc-servo motors with linear encoders and low-friction ball-screws to simple open-loop stepper motors.
Two basic layouts are offered: a shorter, lower profile version with a folded drive train (motor side-by-side with the platform) and a longer, narrow inline version. Both come in two travel ranges of ½ in. (13 mm) and 1 in. (26 mm). XY and XYZ combinations are also available. Four motor options are available: servo and stepper motors in direct drive or gearhead configurations.
In addition to the entry-level open-loop stepper motor variants, closed-loop models with integrated linear encoders are available. Linear encoders provide direct position measurement at the motion platform and provide better accuracy and repeatability compared to conventional motor shaft-mounted rotary encoders. Encoders with 50 nm and 5 nm resolution are offered. The direct drive versions can achieve velocities up to 15 mm/sec, the gear-motor versions up to 1 mm/sec.
For the most demanding applications, such as the fast and precise alignment of optics and photonics components, an XYZ piezo scanner option is also available. An optional high performance photonics alignment controller with integrated algorithms actively and automatically aligns fiber-optic components in less than one second.
