New Rotary Stage with unlimited Motion

09-26-2014 08:10 PM CET | Science & Education

Press release from: piezosystem jena GmbH

With the rotary stage RA–55–40 piezosystem jena enlarges its product line and offers its customers a rotary stage with unlimited motion. With 32’768 steps per rotation and a bi-directional repeatability of 36 arcsec the rotary stage RA–55–40 is excellent suited for applications in research and development, for beam deflection as well as laboratories and industry. The rotary stage RA–55–40 can be driven stepwise or in a continuous mode.

The rotary stage RA–55–40 is driven by a bipolar two phase stepper. A position transducer is not necessary but the RA–55–40 can be equipped with a home referencing. The direct drive construction of the rotary stage RA–55–40 ensures backlash free motion. With the specially adapted controller all necessary parameters can be set up “on the fly”. Parameters include the position, velocity, acceleration and the torque.
Because of the compact design and the low weight the rotary stage RA–55–40 is excellent suited for applications with limited space and for filigree structures. The RA–55–40 can be fixed at a bottom plate via a M4 threaded hole raster at the bottom of the casing. In the moving platform there is also a M4 threaded hole raster to fix customers elements.

Objective Positioners Adapted To Meet Your Needs For Industrial Applications
piezosystem jena has extended the objective positioner series MIPOS with two new industry products. Typically objective positioners are firmly mounted directly onto a microscope. Piezosystem also introduces two new systems, which can be screwed on a machine or rail. MIPOS 140: Most installed lens positioners require an undesired extension to the optical axis. The distance between the lens and the sample is shortened. This can lead to collisions between the optics and the
Incremental Trigger Function
Trigger signals dependent on the position of the stage Digital piezo-controllers from piezosystem jena (d-Drive and d-Drivepro) offer flexible control for customized systems such as cameras, illumination systems, optical shutters or external measuring systems. Now, piezosystem jena can offer a comfortable trigger function. Trigger signals can be generated dependent on the position of the stage: • Rising edge • Falling edge • On both edges in the direction of movement An additional function sends out a trigger

To offer you complete systems for your needs, piezosystem jena has engineered and produced a NEW series of Motion Control Stages and High-Power Piezo-Composite Actuators. The new catalog does not only show our proven, ultra-precise nanopositioning piezo stages for positioning with sub-nanometer accuracy and their appropriate controllers; it also incorporates our powerful Piezo-Composite Actuators and their
Beam Tracking with Mirror Tip- and Tilting Piezostage PKS1
In biology applications a laser beam is used for cell stimulation. First the laser beam is redirected onto 2 mirrors then directed to the cells. An important requirement, to hold the laser beam onto the cell is very difficult to achieve due to thermal effects or external vibration. The position of the laser beam needs to be controlled in real-time to track the motion of the cell. For this task a
