Small Size and High Resolution: New Miniature Stage is Only 24mm Wide at a Resolution of 2nm

LPS-24 series

Physik Instrumente (PI) has introduced the new LPS-24 series. At only 24mm³ × 33mm³ × 20mm³, these new miniature positioning stages provide a travel range of 15mm with nanometer-precision resolution.

The LPS-24 stages fulfil important requirements for the positioning of optical or mechanical components or for the adjustment and manipulation of samples in application environments with a confined space.

For the LPS-24 series, PI uses NEXACT piezo stepping drives. These drives combine the high-precision resolution and stiffness, typical for piezo actuators, with long travel ranges.

For position measurement, a linear encoder with 150nm resolution is integrated into the small-sized stages.

With the PIOne linear encoder, a 2nm resolution is attained when combined with a stage length of 63mm instead of 33mm.

Piezo stepping drives for precision, reliability and long lifetime

The piezo stepping drives offer important advantages for the high-precision positioning of the miniature stages: They perform displacements at an adjustable and constant velocity. Their drive principle is based on a defined actuator motion and exclusively on stiction during the stepping motion of the piezo actuators. This results in a substantial increase in the lifetime and reliability of the drives.

Easy system integration and extensive software

The controller E-861 allows simple and precise operation of the miniature positioning stage. It supports the different types of motion of the piezo stepping drive and is tuned to the requirements of the mechanical system. As a result of the controller’s networking capability, up to 16 controllers can be driven simultaneously via one computer interface.

All parameters can be set and checked via software. For start-up and system configuration, the program PIMikroMove is included in the scope of delivery. Connection to custom software is possible via LabView drivers and DLLs.
