Piezo nano-positioning components supplier.

Overview

Established in 1991, piezosystem jena offers piezo micro-positioning, piezo nano-positioning and metrology solutions to the semiconductor, aerospace, microscopy and synchrotron community. We have an extensive knowledge and in-depth technical expertise in the application of piezo technology for nano-positioning tasks, and in the design of piezo flexure stages and development of piezo-mechanical systems.

The real strength of piezosystem jena comes from our commitment to complete customer satisfaction in the markets we serve. The partnerships we form with our clientele in applications such as super resolution microscopy, AFM, process control, semiconductor metrology and nano-positioning for synchrotron radiation are long-lasting and mutually beneficial. Our knowledge in piezo technology comes from our own research, and our daily interactions as consultants.

  • MIPOS Objective Positioners
    The piezo focus lens positioner series MIPOS is made for high precision and accurate micro lens movement....

  • MIPOS objective/lens positioners allow a microscope or other optical device to precisely focus and act as a piezo scanner with sub-nanometer resolution. These high quality positioners are simple to attach to standard microscopes and provide a quick easy way to upgrade a microscopy system.

    The z-axis actuating system for precise objective positioning is made for applications such as single photon microscopy, laser scanning microscopy, and confocal microscopy. In general, for all kinds of very precise high resolution microscope scanning. The MIPOS piezo lens positioner is able to move the optical objective lens with unique position repeatability in the sub-nanometer range. The piezo objective positioner reacts immediately if the controller signal is adjusted. This solution offers high speed and high dynamic performance as a piezo objective slide scanners, confocal scanners and other types of optical scanners and microscopes.A piezoelectric actuator is mounted in a unique lever transmission design of flexure hinges. The small motion of the actuator, caused by an analog control signal, is transferred to a special point. The sophisticated monolithic guidance design of the solid flexure hinges means the trajectory is free of mechanical play and friction – a feature of all piezosystem jena stages.

    Due to this technology, the motion is parallel to the optical beam. The resolution is very high and in practice only limited by the voltage noise of the power supply. This is why we can guarantee high accuracy only when also using piezosystem jena electronics.All MIPOS systems can be equipped with an integrated positioning feedback sensor to check and control the exact accuracy of these fine focus scanner systems.

  • Piezo NV200/D Controller/Amplifier
    The NV200/D controller is built to deliver powerful high-resolution signals offering a wide variety of control options including ethernet and USB – C. With 400 mA of peak current, the system can provide high frequencies and fast response times....

  • The NV200/D NET is a digital piezo controller with a serial and an ethernet interface for local and remote control and servicing of piezo actuators. The user can drive quasi static or dynamic step positioning applications through the network access, allowing for more flexibility and use in critical environments. For high dynamical applications, a real time SPI inter-face is implemented.The amplifier can drive piezoelements with up to 400 mA.


    With a 16 bit resolution, the NV200/D NET guaran-tees high positioning accuracy and low noise.
    The NV200/D NET can automatically recognize actu-ators and adjust control parameters from stored information in the EEPROM connector. The NV200/D NET can be used with actuators equipped with either strain gauge or capacitive sensors, as well as with actuators without measurement system. The NV200/D NET also supports actuators based on pie-zosystem jena’s own NanoX® bi-directional actuating technology.


    Features:


    The NV200/D NET has an automatic sensor calibra-tion (ASI / ASC) function. All values of the actuating system, like serial number of the actuator, actuator name, control parameters and filter settings, are stored in the actuator plug. This allows an easy ex-change of actuators or controllers.


    A digital PID controller is integrated in the device. The user can change the values according to his or her current setup. For repetitive motion patterns, an iterative learning control (ILC) algorithm can be used to achieve highest tracking precision. In this way, the NV200/D NET can achieve closed loop precision at open loop speeds. Due to its trigger input and output functions additional units of the NV200/D NET can be synchronized to control multiple axes.

  • PSH 25 Tip-Tilt Stage
    The PSH 25 serves the fast and precise positioning of optical components. Mirrors or prisms can be positioned in the mrad range at up to several hundred kilohertz....

  • This tip-tilt steering mirror platform is characterized by the positioning of optical components in two axes. A tilting range of up to ±20 mrad (open loop) / ±16 mrad (closed loop) is available. Another key feature is the easy exchange of different optical components.

    The tilting system PSH 25 can be equipped with an integrated strain gauge positioning sensor. Positions can be controlled very exactly and a previously established tilt range can be set and repeated.

    Optics and optical components in various sizes can be mounted on to this tilting system.
