1. Turn the condenser height fine adjustment knob @ counterclockwise to
loosen it, then push it fully to the right to raise the condenser to the higher
limit of fine adjustment.
2. Turn the condenser height adjustment knob ² in the direction of the ar-
row to lower the condenser to the lowest limit.
3. Set the aperture iris diaphragm lever ³ to open ( –> \).
4. Set the field iris diaphragm lever | to open ( –> \).
5. Use a 10X objective and bring the specimen into focus.
6. Stop down the field iris diaphragm lever until the field iris diaphragm
image comes inside the field of view.
7. Gently push the condenser height fine adjustment knob @ to the left to
bring the field iris diaphragm image into focus. When it is focused, turn the
knob clockwise and fix it there.
8. While gradually opening the field iris diaphragm, turn the condenser-
centering knob ƒ on the condenser holder so that the field iris diaphragm
image comes at the center of the field of view of the eyepiece.
9. Gradually open the field iris diaphragm until its image inscribes the field of
view. Now the DIC condenser is centered.
}In actual observation, open the field iris diaphragm until its image circum-
scribes the field of view.
