Adjusting the Condenser Position and Aperture Iris Diaphragm
(Fig. 14)
}The condenser is usually used in the highest position. If the entire observed
field of view is not bright enough, brightness may be improved by lowering
the condenser slightly.
1. Rotate the condenser height adjustment knob 1 to move the condenser
to the highest position.
2. The aperture iris diaphragm ring 2 has an objective magnification
scale (4X, 10X, 40X, 100X). Rotate the ring so that the magnification
of the objective in use faces frontward.
