Miniature positioning stages of the LPS-24 series: As small as 24 x 33 x 20 mm³ and with nanometer precision

Miniature positioning stages of the LPS-24 series: As small as 24 x 33 x 20 mm³ and with nanometer precision

Physik Instrumente (PI) has introduced the new LPS-24 series. At only 24 × 33 × 20 mm³, these new miniature positioning stages provide a travel range of 15 mm 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 150 nm resolution is integrated into the small-sized stages.

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

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 dis-placements at an adjustable and constant velocity. Their drive prin-ciple 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.

New piezo nanopositioning system: versatile, fast and compact with large clear a …
Large clear aperture, high control dynamics, fast settling times and compact dimensions: PI launches a new product line of linear nanopositioning systems for a broad range of applications. The P-630 stages are perfectly suited, e.g. for use in sensor heads or precision motion of objects in optical and tactile metrology as well as for microstructuring. With travel ranges up to 80 µm and a direct piezo actuator drive, the compact positioning
2 mm Travel Range - 20 Milliseconds Settling Time: New Objective Scanner with Pi …
New microscopy methods, such as two-photon microscopy, make it possible to record 3D stacks with up to 1 mm depth in biological samples. For this they require high-performance drives for positioning the objectives. PI (Physik Instrumente) now developed the new N-725 PIFOC® objective scanner with piezo stepping drives especially for position-ing microscopy objectives. The N-725 provides travel ranges of up to 2 mm along the optical axis. At the same time
New Version of M-663 Micropositioning Stage: Benefits of PILine® Drive Technolo …
Cost-effective with 2 µm step size. PI (Physik Instrumente) completes its product line of high-velocity M-663 micropositioning stages. The new linear stage version M-663.5U is especially suited for positioning tasks in automation where a resolution of 0.6 µm and a step size of 2 µm are sufficient. The integrated PILine® linear motor provides push forces to 5 N and a maximum velocity of up to 250 mm/s over a 18 mm
Modular Hexapod System for Fast, Economic and Precise Positioning
PI presents a modular concept for six-axis positioning systems. Due to its modularity, the high-precision parallel kinematics can be adapted fast and efficiently to customer requirements. The six identical Hexapod struts are designed such that their length can be easily scaled. They include the required electronics for reference point switches, limit switches, position sensors and electronic commutation for the brushless DC motors. Their standardized joints allow to combine them with almost

New temperature sensors in miniature design
Klingenberg, January 2014. They are so small that you hardly notice them: With their minimal design, the new temperature sensors from WIKA fit in even the tightest of spaces. The model TF40 was developed specifically for use in ventilation ducts; the model TF41 for the measurement of outside temperatures. The measuring elements of both sensors are inserted into a UV-resistant plastic housing that measures just 44(l) x 32(w) x 30(h) mm. The
