Microscopy

Modern tasks in microscopy require higher imaging resolutions and
scanning systems for 3D imaging. New special optical methods (like STED,
TIRF, CARS, DIC) were developed to get more and more detailed information
in the field of biology as well as other applications.

  • Auto focus applications
  • Systems for confocal microscopes and 3D imaging
  • Positioning systems for modern investigation methods like STED; TIRF; DIC ... ; 2 Photon Microscopy
  • Positioning systems that can be integrated to almost all major
    microscopes

Optics, Laser technology

Lasers are used in almost all areas of our life. Complicated lasers and
optical systems require very fine adjustments and stable positions of
their components. Piezoelectric stages are used for:

  • Adjustment of optical systems and lenses
  • Mirror adjustment, fast tilting and scanning
  • Interferometry

Metrology

Inspection of surface structures on wafers or flat screens using different
optical methods require more and more precise motions. Demands
for faster cycle times for inspection tasks require lower response times.
Piezoelectric actuators and scanning stages from piezosystem jena can
guarantee to fill these needs, they are used in:

  • AFM, Atomic Force Microscopy
  • Fast scannings
  • Material research

Fiber Switches, Optical Multiplexer

Applications for optical switches are in spectroscopy and in quality control of production lines.

Fiber switches from piezosystem jena are developed to switch light in optical multimode fibers between different channels. Switches with up to 18 channels are available. Because we use direct switching without optical elements in the light path, the spectral range is not changed by the switch. Based on the use of piezoelectric drives a fast switching time in the milliseconds range can be achieved.

Industry Applications and Research

OEM stages are perfectly fitted for various industry applications. The “Pure Edge 240 Collimator” is an example for a synchrotron application. This system provides different size beam-squares very precisely within a few milliseconds. The device is based on 2 orthogonally oriented piezo slits “PZS 4 SG”.

Technology of Piezo Stages

Actuators for Fast Direct Movement

The technology is based on piezoelectric actuators. An electrical signal is applied to a piezo - ceramic actuator. Thereby the actuator then expands very precisely based on the piezoelectric effect.

The piezoelectric effect depends on different parameters, e.g. length of the ceramic and applied voltage. An actuator with a total ceramic length of 10 mm generates an expansion of about 10 - 15 ?m. Depending on the quality of the electronics, a motion with a resolution of less than 1 nm can be achieved.

Piezoelectric actuators can generate forces up to several kN and operate very fast with frequencies up to several kHz.

Actuators with magnified motion based on solid state hinges

Some applications require a range of motion larger than 10 ?m or 100 ?m. Therefore piezosystem jena combines its piezo-ceramic actuators with a special construction of solid state hinges to magnify the range of motion.

These piezoelectric stages can:

  • Generate motions up to 2 mm
  • Realize sub nm resolutions
  • Work extremely fast (scanning, vibrations, pulses, up to 60 kHz)
  • Operate under vacuum conditions and at low temperatures

Piezocomposite Actuators

Piezocomposite actuators can generate pulses with accelerations of up to 10.000 g, high dynamic vibrations with frequencies of more than 100 kHz and forces of several tens of kN.

To achieve these performance characteristics, several layers of ceramic plates are stacked and combined. Different ceramic materials and housing cases can be combined to achieve better dynamic parameters compared to conventional multilayer piezo-technology.

Ring type actuators allow high dynamics due to an effective cooling throughout the actuator. They are often used in laser applications due to their center aperture.
