Страница: 34 / 62

This chapter describes retooling tasks for changing the Operetta`s optical setup and
maintenance procedures, which need to be carried out periodically to keep the
instrument in good operating condition.
The individual steps for each task are described and a schedule for the maintenance
tasks is given.
Danger!
Do not attempt to perform any kind of maintenance or retooling on
the Operetta beyond those listed and described here! All other
technical service tasks – including but not limited to those described
in the Service Manual – may only be performed by the PerkinElmer
service personnel.
The retooling and maintenance steps outlined in the following may be carried out by the
user. Please be sure to follow the instructions closely and observe both the general
safety instructions (see chapter 1 "System Safety", page 5), and any specific safety
instructions which may be given at the beginning of each section.
3.1 Retooling
3.1.1 Objective Lens
The motorized four position changer can automatically change objectives. The user
has the choice of 10x, 20x, 40x, 60x and 100x objectives. There is a wide range of
objectives available, optimized either for high numerical aperture / resolution or high
working distance for thick bottom plates or thick sample carriers. The 20x long WD
objective is always included in the instrument.
All of the other selections can be chosen as an option when purchasing the instrument,
or at any other time for customer installation. Objectives are barcoded and can be
exchanged by the user. Up to four objectives can be fitted onto the objective turret for
automated change.
