Nanomotion’s Z-Axis Auto Focus Stage
Date: 12 March 2008
High performance miniature motorised translation stage combines ceramic motor, encoder, precision bearings and counterbalance.
Auto Focus Stage provides positioning and
focussing for microscope and imagain applications.
With high speed performance for both long travel and nanometre to
micron range incremental moves, Nanomotion's motorised Z-Axis Auto
Focus Stage provides a complete vertical positioning and focussing
solution for automated microscope and imaging applications.
Available exclusively in the UK from Heason Technology, the compact
stage is easily adapted to standard or custom microscope mechanics
and is available with a wide range of matching servo drives and
motion controls.
The Z Axis Auto Focus Stage assembly combines Nanomotion's unique
standing wave, inverse piezoelectric ceramic motor technology and a
high resolution encoder in a miniature but robust translation stage
housing with integral precision bearings and a spring
counterbalance.
The zero backlash, direct-drive stage features a travel range to 25
mm, selectable standard resolution from 10 nanometres to 100
nanometres (with 1 nanometre optional), a wide dynamic speed range
(up to 250mm/second) and static loading to 400 grams.
Nanomotion's ceramic servo motor technology suits the demands of
high-speed move and settle positioning required by microscope
focussing applications, providing a typical focussing move of 1 to
10 microns in under 5 milliseconds, settling within 100 nanometres.
Ultra fast settling times and the inherent ability to lock the
stage's position at rest and under power-of conditions ensures
excellent levels of optical stability with minimal thermal
drift.
Typical applications for the Z Axis Auto Focus Stage include
managing the demanding high speeds, accelerations and positioning
reversals in cell terrain imaging, semiconductor and biomedical
microscopy, and on-the-fly focussing. The stage may also be used in
a horizontal orientation for step and repeat imaging.
