Miniature Linear Stages, Miniature XY-Positioning Stages, Compact XYZ-Linear Stages

Products - PI (Physik Instrumente) L.P.

The new L-505 motorized miniature linear stage series provides high precision motion in a very compact package. Single axis, XY-table, and XYZ-linear actuator combinations can be assembled including a large variety of stepper motor stage and closed-loop servo motor stage options, lead screws, and fast, low-friction ball-screws.

Two Basic Stage Designs: Folded and Inline

Two basic designs of the miniature linear translation stages are offered: A 60mm wide, shorter, lower profile (21mm) version with a folded drive train (motor side-by-side with the platform) and a longer, narrow (36mm) inline version, 25mm profile. Both come in two travel ranges of 1/2” (13mm) and 1” (26mm).

XY-Linear Stage and XYZ-Linear Stage Combinations

Miniature XY-stage combinations can be assembled without adapter plates, for XYZ-linear stage assemblies a Z-bracket is available (see image).

Motor Options
L-505 miniature stages are available as stepper motor linear stages and servo motor linear stages, both with gear-head and direct drive configurations.

High Resolution Linear Encoder Feedback for Closed-Loop Positioning Operation

All but the open-loop stepper motor stage variants come with integrated linear encoders. Linear position encoders provide direct position measurement at the positioning table platform and provide better accuracy and repeatability compared to motor shaft-mounted rotary encoders. The encoder resolution is 5 nanometers for stepper motor stage versions and 50nm for servo motor stage versions.

Velocity: Linear Motion Up to 15mm/sec

The direct drive motor versions of these compact linear translation stages can achieve velocities up to 15mm/sec, the gear-motor versions up to 1mm/sec. When high-speed motion is required, direct-drive stages are recommended.

Combination with Piezo XYZ Actuators / Scanners for Photonics Alignment

For the most demanding motion and positioning applications, such as the fast and precise alignment of optics and photonics components, a piezoelectric XYZ actuator / scanner option can be added to the L-505 miniature linear translation stages.
