3. Put the sample on the adhesive tape and carefully press it with tweezers in several
places (not touching the area intended for the investigation).
ļ NOTE. After the sample is fixed on the substrate, a noticeable vertical drift of
the sample can occur within one hour (due to the slow relaxation of sticky tape).
This drift should be taken into account. If the task requires the minimum drift,
prepare the sample beforehand (at least, an hour before the investigation).
4. Place the substrate with the sample on the sample holder. Insert the substrate from
aside under the spring clips (Fig. 3-3).

ļ ATTENTION! When working with a thick sample, you need to account for
its height in the program. The default value of the sample is set to 0.5 mm
(For more details how to set up the sample height see page below).
5. Place the sample holder on the scanner (Fig. 3-4). To this purpose, take the holder
with its larger hole being directed to you and carefully pin it on the end of the optical
tube avoiding contact with the tube lens. Then, mount the sample holder on the
magnetic fastener of the scanner (Fig. 3-4). Make sure that:
- the holder magnetic disk comes to the center of a magnetic holder and lays on the
three support balls;
- axis of the optical tube is horizontal and comes to the center of the lateral orifice
of the holder. This ensures that the spring clips of the holder will not damage the
probe and will not obstruct approaching the sample.
- Notice that with proper alignment of the sample holder, the clips are slightly
turned to the axis of the optical tube.
