MOT
microscopes, make sure to read
the notes on instrument safety and the Description (Chapter 1) and Start-up (Chapter 2)
chapters.
(1)
As described in chapter 2, the microscope is ready for operation and switched on according to
section 3.3.
(2)
Place a high-contrast specimen on the mechanical stage (cover slip pointing upwards).
(3)
Swing in 10x objective on the nosepiece and focus on the specimen; if possible, always move
the specimen away from the objective!
(4)
Move condenser 0.9 (in brightfield position, front lens switched in) to the upper stop position
via the condenser drive. The height adjustment must be set in such a way that the specimen is
not touched by the condenser.
(5)
Close luminous-field diaphragm until it is visible in the field of view, even if not in focus
(Fig. 0-1/
A
).
(6)
Lower universal condenser 0.9 until the edge of the luminous-field diaphragm appears in
focus (Fig. 0-1/
B
).
(7)
Center luminous-field diaphragm using centering screws on the condenser carrier (Fig. 0-1/
C
)
and open it until its edge just disappears behind the field of view (Fig. 0-1/
D
).
(8)
To set the aperture diaphragm (contrast), remove one eyepiece from the binocular tube and
set the aperture diaphragm to approx. 2/3 of the diameter of the objective exit pupil
(Fig. 0-1/
E
). Optimum contrast setting is dependent on the respective specimen.
(9)
Insert eyepiece again and, if required, refocus on the specimen via fine drive.
(10)
After each objective change, field size and objective aperture change, which makes it
necessary to repeat steps (5) to (9).
(11)
For objective magnifications between 1.25x and 5x, the front lens 0.9 of the universal
condenser must be swung out and the aperture diaphragm opened entirely.
