TRITOR^® nanopositioners are extremely compact but offer motions of up to 400 µm in all three X, Y and Z axes. Parallel motion is achieved without mechanical play due to the system’s rigid design. As an option, integrated position control systems for overcoming the effect of hysteresis are available.

These piezo stages can be easily combined with other mechanical positioning systems, and they are well suited for various applications reaching from optical research to OEM systems.

TRITOR^® elements consist of actuators integrated in a housing with internal lever transmission. Since the lever mechanism works in both directions, forces between the housing and top plate need to be avoided, as they could damage the stage.

These multi-axis positioning stages are attached by using two diagonal holes.

piezosystem jena offers multiple ranges of amplifiers and controllers, from one-channel, multichannels, modular and high power amplifiers.

Fast Steering Mirrors, or FSMs, from piezosystem jena play critical roles in modern optical inter-satellite communication terminals.

As the workhorse of these terminals, an FSM allows for the stabilization and precise pointing of laser links between satellites. This is vital as a stable and secure connection is absolutely necessary for the efficient and consistent transfer of data. Especially in low earth orbit, atmospheric turbulence along with onboard vibrations can cause misalignment and link breakage. FSMs provide a solution by countering these vibrations through extremely fast and precise motion.

Our FSMs:

• Displacements up to ±20 mrad.

• Sub-microradian resolutions.

• Closed-loop strain gauge feedback for elimination of hysteresis and drift.

• Bandwidths up to 6500 Hz.

Piezoelectric driven switches are especially designed for fast switching – measured in milliseconds – low loss and high repeatability. Piezo actuators enable the optical switch to couple optical fibers with an accuracy of a few microns.  The high accuracy of positioning of the piezo-electric actuators guarantees a light transmission of >80%.

Standard switch configurations range from 1-input to 2-outputs, up to 1-input to 9-outputs. Fiber switches can also be used the other way around,from 2-inputs to 1-output, up to 9-inputs to 1-output. Standard fiber diameters range from 50 to 600 micrometers. A variety of connectors are available.

piezosystem jena fiber switches use fiber surface coupling. The major advantage of this design is that it is not necessary to depend on optical components in the switcher. Fiber switches with optical components, like lenses or prisms, will always result in a wavelength-dependent limitation.

The small size of the fiber switch and the easy control make these fiber optic switches ideally suited for use as components of spectrometers or other metrology devices. Switch systems with many more output channels can be achieved by cascading multiple fiber switches.
