IC Inspection Microscope ECLIPSE L200ND / L200N Instructions
4.7
Attaching the objectives
Lower the stage to the limit. Insert the objectives starting from the lowest magnification into
the sockets for the nosepiece addresses from 1 to 6 in numeric order.
The objectives of
∅
25 mm and
∅
32 mm screws can be attached to the revolving nosepiece.
Note that the
∅
25 mm objectives need objective mount adapters to change their screws to
∅
32 mm, whereas
∅
32 mm objectives fit the revolving nosepiece without an adapter.
4.7.1 When removing the objectives
To avoid breaking the objectives and the sample, first lower the stage to the limit and
remove the sample on the stage. Then remove the objective using both hands so that the
objective will not fall out suddenly.
4.7.2 If the objectives are out of the optical path when they are switched
If the objectives are out of the optical path when they are switched, turn the revolving
nosepiece several times. After these several turns, the objectives will be set correctly on the
optical path. This trouble may happen when there are only a few objectives on the revolving
nosepiece, and all the objectives are set on one side of the revolving nosepiece.
4.8
Attaching the eyepieces
Attach eyepieces with the same magnifications for the left and the right eyes.
There is a positioning pin on the binocular part sleeve. Insert the eyepiece so that its
positioning groove matches the pin.
4.9
Installing the filter block (for fluorescent illumination only)
CAUTION
•
Turn off the power switch of the microscope (flip the switch to the “
c
” side) when installing or
replacing the filter block.
•
If you replace the filter block while the episcopic illumination is turned on, the strong light may
hurt your eyes.
1.
Loosen and remove the dark-field/bright-field/fluorescent selection lever.
2.
Remove the lid on the right of the arm.
•
Loosen the knob until it is removed together with the lid.
3.
Mount the dark-field/bright-field/fluorescent selection lever and draw it out to near side.
