Two light path settings are possible:
Switching rod complete in the unit:
In the first position according to the table, all light goes to the eyepieces. The camera port
receives no light.
Switching rod completely out of the unit:
In the second position according to the table, all light goes to the camera. The camera port
receives all the light. This is especially helpful when using contrast techniques or observing
moving / living samples as exposure times are the shortest.
