Using the field iris diaphragm ring @, adjust the diameter of the field
iris for objective power to the extent that it just circumscribes the field
of view. When the field iris diaphragm is stopped down to circumscribe
the field of view, it will exclude extraneous light and improve image
contrast within the field of view.
#When using the 100X objective, the field iris diaphragm image will
not be visible within the field of view. Accordingly, stop down the
diaphragm to its smallest diameter.
