Aerotech's nano translation
Aerotech's nano translation (ANT) stages, which are aimed principally at
the fibre optics manufacturing sector, offer a closed loop resolution of
100 Angstrom, with resolutions of 2.5nm (linear) and 0.045 arc seconds
(rotary). Even at these resolutions, ANT stages are capable of travelling
at speeds in excess of 250mm/s. Thanks to the use of linear motors, the
positioning stage is non-contacting, keeping maintenance requirements to
a minimum. Other benefits include no cogging, hysteresis or backlash, and
no loss of accuracy over time.
