RoboStage
The computer controlled PALM® RoboStage is a
motorized specimen stage especially designed for
high-precision laser micromanipulation in sub-
micrometer range. Its movement is carried out by
two stepping motors at a speed of only a few µ-
meters up to several mm per sec. and displayed
largely vibration-free between 1µm and approx.
70mm. The stepping motors are controlled by two
encoders that are affixed below the stage.

RoboStage
Several special functions are integrated to speed
up routine work.
In PALM
®
RoboStage there is a holding frame into
which the specimen slides and/or Petri dishes can
be clamped.
Both transversal sides of the object slide are held
by a snap-on clip. One longitudinal side of the slide
entirely rests on the holding frame.
This reduces the risk that extremely thin slides will
bend by the adhesion force of the immersion oil.

Caution
Do not move the stage manually!
Do not touch the moving stage!
Caution
Avoid contaminating the guide of the stage
with oil or chemicals. Avoid any kind of
mechanical stress, e.g. putting heavy parts on
it or leaning against, as it is a precision instru-
ment.
Notice
Do not clean the stage with alcohol!
