The double tilt translator DTT is based on 2 pairs of APA35XS. Three types of movement can be generated:
♦ Z movement (translation) up to 35 μm, when the two pairs of APA35XS are simultaneously
actuated,
♦ ΘX and/or ΘY movements (tilt) up to +/- 2 mrad, when the two actuators of a pair are
actuated in opposite phase.
The double tilt translator mechanism can be based on actuators equipped with strain gauges to eliminate the hysteresis. To obtain the three movements, four electrical channels are necessary. If only the two tilts are required, then only two channels are necessary (with the Push-pull mode from the 75 family of drivers).
