3.9 Revolving nosepiece and objectives
Depending on the dimensions of the objectives, the revolving nosepiece allows for the
attachment of up to four objectives. Objectives with different magnifications and objec-
tives for special IR spectroscopic measurement techniques (e.g. ATR
1
, GIR
2
) are avail-
able.
1. ATR - Attenuated Total Reflection (abgeschwächte Totalreflexion)
2. GIR - Grazing Incidence Reflection (Reflexion bei streifenden Lichteinfall)

Fig. 3.15 Component and explanation
A Revolving nosepiece: to attach objectives at the microscope and to posi-
tion the desired objective in the beam path with which you intend to work.
Note: Depending on the dimensions of the objectives, up to four objec-
tives can be attached at the nosepiece at the same time. To place an
objective in the optical path do NOT rotate the nosepiece by gripping an
objective but the nosepiece itself. Rotate the nosepiece until the wanted
objective is in the optical path. The nosepiece snaps automatically into the
exact position, i.e. it clicks into position.
B Objectives
Figure 3.15 shows the following objectives:
• 15x Schwarzschild objective (This objective is designed for both sample
viewing and IR spectroscopic measurements.)
• 4x glass objective (This objective can be used for sample viewing only.)
Note: These two objectives are included in the standard delivery scope.
For an overview of the optionally available objectives, see section 5.1.1.
C Two vacant positions: If not used, they are covered with caps.
Note: Before attaching an objective, remove the cap.
