Physik Instrumente has introduced the new LPS-24 series.
The company says that, at only 24 × 33 × 20mm, these new miniature positioning stages provide a travel range of 15mm with nanometre-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.
