Operation 4
7. Mask off that sample area which is
not intended for spectroscopic analy-
sis.
Note: In case of the ATR objective, the
measuring spot diameter is about
32 µm.
Manual knife-edge aperture (D in
fig. 3.10 and fig. 3.11)
Motorized knife-edge aperture (F in
fig. 3.10) This aperture is operated by the
corresponding OPUS functions.

8. Move the stage downwards. Manual stage and motorized x/y-
stage: coarse and fine focus knobs at
the microscope (B/B’ and C/C’ in fig. 3.7)
Motorized x/y/z-stage: Joystick and cor-
responding stage control functions in
OPUS

9. Exchange the sample for the plastic
ring. Place the plastic ring underneath
the ATR objective.
Note: The plastic ring is included in the

acoustically by a beep and optically by
the In-focus LED
. When the ATR crys-
tal has reached the focus position, the
In-focus LED turns from red to green
for a short moment. Then it goes off.
