The Ratis features:
15
► Ratis – plane-parallel device for positioning / scanning.
The device is a monolithic metal body (usually made of high
quality aluminum alloy), in which EDM wire-eroding and
other methods of precision machining formed channels for
154°
piezoceramic actuators, mobile elements of stage, etc.
This design provides excellent linearity and flatness of the
45
movement, in contrast to the classical scanners based on
6 BALLS 4
piezoelectric tubes, the surface scan which is in the sphere.
In addition, the plane-parallel scanners have high mechanical
50.5
strength, compared with fragile piezoelectric tubes.
48
► All axes Ratis scanners are equipped with capacitive
displacement sensors included in the chain of digital
42
feedback. It provides high accuracy and linearity of
8x 3
movement, eliminates the effects of drift (creep)
piezoceramics. The measuring part is based on TDC
(time-to-digital converters) that are physically located
as close to the sensors, and immediately issue a digital
signal proportional to the measured capacitance.
This minimizes the influence of external electromagnetic
noise, and use long cables to connect the scanner
to the controller.
41
►Control Ratis scanning stage by means of a universal controller EG-3000
46.5
and software NSpec.
► Actually, plane stage Ratis + fully functional SPM controller EG-3000 universal software NSpec are complete
scanning, data acquisition and visualization system, which is a “heart” of any scanning microscope, and
perfectly fits for any “home made” systems. Customer, which task is using own home made nanosensor of
some physical signal to obtain it’s distribution at nanometer scale, purchasing such a product , saves his
scientific project time and resources.
► Electronic controller EG-3000 is designed to control SPM or confocal microscope performance. Controller
provides data acquisition from system sensors and external devices, applies control voltage to scanners
piezoelectric actuators, all obtained information is transferring to PC work station for visualization and
processing. Control signal is transferring from PC to controller for adjust all system parameters. One of the
most important parts of the EG-3000 controller is closed loop feedback system. Based on a high quality
20-bit TDC (Time to Digital Converter) to measure displacement capacitance sensors. Any available system
signal can be used for SPM feedback. Controller is capable to operate 6 channels with feed back
simultaneously, which allows to scan by tip and by sample both.
► EG-3000 SPM controller contains 2-channel lock-in amplifier to provide resonant SPM techniques, for
example non contact SPM mode. Lock in amplifier includes high stable voltage generator based on digital
frequency synthesizer. High speed data processing implemented, using programmable logic (PLIS), allows
to perform high quality lock in performance up to 1.5 MHz band.
► EG-3000 has malty channel (up to 12) stepping motor control with micro step option for rough adjustments
of scanning head (stage).
► Controller has external analog inputs and outputs for external equipment connections, sync inputs and
outputs. Connection with PC work station is provided via USB interface. Universal software Nspec,
designed for using with EG-3000 has wide range of possibilities for data processing, which allows to
implement set of modern SPM techniques. NSpec is capable of running under different operation systems.
