6-Axis Miniature Vacuum Positioner

Video Hexapod controlled by iPad  (http://www.youtube.com/v/HJloDFTaSPc)

Positioning applications within vacuum chambers have high demands on the components used.  The installation space is restricted and at  the same time, a high degree of flexibility is needed in positioning objects so that the vacuum chamber does not need to be opened frequently. The new M-811.STV Miniature Hexapod offers the perfect solution. Based on the even smaller M-810 Hexapod, this new design provides twice the stiffness in the horizontal axes.

Low Profile Rotation Stage now with  Higher Resolution

One of the lowest profile stages on the market, the M-660 rotation stage, is now complemented  by a higher-precision model providing more than the 8 times the position resolution of the existing version.  

 - Very low profile: <15 mm
 - Resolution 4 μrad (0.00023°)
 - 35 mm Aperture
 - Fast: up to 720°/sec

Microscope Scanning Stage Upgraded with Capacitive Sensors 

 

PI has added two higher-performance models to its successful PInano™ superresolution (SR) microscope stage series.The new models are equipped with direct-measuring capacitive sensors. This type of sensor can provide higher linearity and long-term stability than the lower cost piezoresistive sensor-equipped stages which are still available. Capacitive sensors are also less sensitive to noise due to a high-frequency measurement principle as opposed to the DC-based sensing technique used in piezoresistive sensors. The net effect is similar to the higher quality and lower noise on FM radio channels compared to AM radio.

More Affordable Piezo Flexure Actuators 

   

PI offers a number of newly designed, low-cost flexure actuators for OEM applications.
Traditional Piezo Mechanisms Use
Piezo actuators and positioning systems are traditionally known for their extremely high precision in the sub-nanometer realm such as required in atomic force microscopy, nanotechnology and semiconductor applications. The extreme precision has given this cutting edge technology a reputation for high cost. 

However
Piezo actuators can do a lot more than "just" nanometers. Their excellent dynamics and high force play a crucial role in many areas, where the (nanometer) precision is of lesser importance: e.g. for fast switching, vibration cancellation, or to adjust tools in machines. In these applications the piezo actuator is one - if not the only - solution.
PiezoMove Flexure Mechanisms
PI PiezoMove flexure-guided actuators provide high precison, fast response and travel ranges to 1000µm and more. They are completely frictionless don't require lubricants or maintenance and have lifetimes of several billion cycles.  PI provides open-loop flexure actuators (for applications where the absolute position is not critical) and closed-loop actuators with internal position sensors, for nanometer repeatability. 

Flexure actuators are often used for microfluidics, fast (medical) pumps, microdispensing applications and as drive components in nanopositioning tables and actuators.

Piezo Stages in Materials Testing / Nano-Indentation 

   

Nanoindentation is derived from the classical hardness test but is carried out on a much smaller scale. It can be used to determine the hardness of thin layers, as well as material properties such as elasticity, stiffness, plasticity, and tensile strength, or fracture toughness of small objects and microsystems in fields such as biotechnology. These measurements involve applying a small force to a sample using a sharp probe and measuring the resultant penetration depth.
