Focus by moving the stage slowly
upwards until the ATR crystal is
pressed in the focus position by plastic
ring or the sample. In case of a man-
ual stage or a motorized x/y-stage, use
the fine focus knobs (C/C’ in fig. 3.7).
In case of a motorized x/y/z stage, use
the joystick.
Note: The focus position is indicated
acoustically by a beep and optically by
the In-focus LED

crystal has reached the focus position,
the In-focus LED turns from red to
green for a short moment. Then it
goes off.
Red: ATR crystal is not in focus posi-
tion.
Green: ATR crystal is in focus position.
Note: In case the ATR crystal is in the
viewing mode position, the In-focus
LED does not light at all.
