The compact M-810 has a smaller diameter than a CD, but offers large travel ranges in 6 axes and excellent positioning resolution

The compact M-810 has a smaller diameter than a CD, but offers large travel ranges in 6 axes and excellent positioning resolution

The tried-and-tested parallel kinematics hexapod systems from Physik Instrumente (PI) provide precise positioning in six axes with precisions below 1 µm.
The new miniature M-810 hexapod takes up only minimal installation space. With a diameter of only 10 cm and a height of 118 mm it provides travel ranges up to 40 mm in the XY-plane and up to 13 mm in the Z-direction. The high-precision brushless special DC motors and high-resolution encoder give each individual strut a positioning resolution of a mere 40 nm. The mini-hexapod reliably positions loads up to 5 kg and achieves speeds of up to 10 mm/s.
Despite its compact size, the necessary driver electronics have been integrated into the base platform of the mini-hexapod. The control is 100% compatible with all previous hexapod models and is conveniently executed via an Ethernet connection. As with all PI hexapods, the position can be entered with commands in Cartesian coordinates.
Parallel kinematics systems have several advantages over stacked multi-axis positioners. All six actuators act on a joint platform, which keeps the moved mass low. Moreover, there is no summation of the lateral runout and tilts of individual axes. The pivot point can be selected as desired via software commands and thus remains independent of the movement.

Well-known for its high quality, PI has been one of the leading players in the global market for precision positioning technology for many years. And PI has been developing and manufacturing standard and OEM products with piezo or motor drives for 40 years. In addition to its three German factories, PI has eight subsidiaries and a total of 500 employees worldwide.

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

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
Small Size and High Resolution: New Miniature Stage is Only 24 mm Wide at a Reso …
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
