5. Move the stage slowly upwards until you see a sharp image.
It is the mirror image of the ATR crystal tip which shows possible fissures and / or frac-
tions in the crystal. See fig. 6.4.
If the check should reveal that the ATR crystal is damaged, it needs to be replaced. For
the order number of a replacement crystal, see appendix C.
6.4.3 Replacing the ATR crystal assembly
General information
The supplied replacement crystal is mounted on a holder. In case of a damaged ATR
crystal, the complete assembly (i.e. holder with crystal) needs to be replaced.
As the very small fastening elements (screws, washers, springs and pins) may easily get
lost during the replacement of the crystal assembly, a complete set of mounting hard-
ware as spare parts is included in the delivery scope of the replacement crystal as well.
NOTE
➣ Do not view through the binocular while moving the stage upwards, but keep an
eye on the decreasing distance between ATR crystal tip and stage. Potential risk
of damaging the ART crystal! Prevent the ATR crystal tip from hitting against the
mirror or the microscope stage.
