Direct the light beam towards a projecting
surface (wall) which is at least 3 m away.
CAUTION
Never look directly into the light-
emitting aperture of the illuminator!

an Allen wrench (AF 3) until both images of the
lamp filament appear as sharp as possible on
the projection surface.

the gaps of the reflected image (

Mount the illuminator on the microscope stand again and tighten the clamping screw to lock it.
•
If applicable, remove the filter from the beam path.
•
Focus the objective
≤
40x on the flat specular surface of a sample and go to a free area of the
