General Description
The Autoscan AS3000i microscope stage is a 2-axis model which was
especially developed for the spatially constrained needs of inverted
microscopes, but can also be used with standard upright microscopes,
and replaces our previous model, the AS3000B. For 3-axis applications,
the AS3000i can be converted to 3-axis movement by the addition of the
AS3500 focus-only attachment (which then creates the AS3000i/f
combination). In keeping with the tradition of our previous AS3000B
stage (which was able to be used only with upright microscopes), the
AS3000i/f features superior mechanical accuracy, stability and general
performance.
Instead of using a stepper motor to achieve focus drive, the AS3000i/f
uses dc motors with optical encoders on all three axes. In combination
with the EL300 electronic controller, this stage achieves outstanding
motion control. It is the finest microscope stage in the world, and
incorporates integral focus. The EL300 electronic controller comes with
a universal power supply, which will automatically adapt to ac supply
voltages between 85 to 264 Volts and a range of supply frequencies from
47 to 400 Hz. Where possible, we supply electrical plugs which match
those in use in our client countries. We use the information shown in a
table on the website of Korjo Pty. Ltd., a major manufacturer of
adapter plugs and other travel products. Please check out the table
shown under "Adapter Guide" at http://www.korjo.com and let us know if there are any inaccuracies for your area.
By means of the optional addition of external linear sensors, it is
possible to further improve the positioning accuracy of our stages. In
the case of SONY sensors, this results in a resolution of 50 nanometers
in all axes, and in the case of Renishaw sensors, a resolution of 100
nanometers in all axes.
Since the use of the combination of extreme optical magnification
(typically x1000 in fission track dating) on the one hand, and extreme
positioning accuracy on the other hand, places stringent requirements
on the mechanical stability of the microscope, we strongly recommend
the use of an anti-vibration base. This can be as simple as a
substantial slab of granite resting on appropriately sized inflated
inner-tubes, or could consist of one of a generally available range of
commercial anti-vibration tables, and may even be as elaborate as the
"dynamic" anti-vibration table models, which continually adjust their
behaviour in response to external vibrations. Please refer to the
appropriate pages on this website for related recommendations and
information.
