Assembly

}The AS unit can be mounted in the same manner as the SZX-EPA eyepoint adjuster, which is described in section 9-1.

Using the Aperture Iris Diaphragm

}By adjusting the aperture iris diaphragm, it is possible to improve the contrast of the observed image and increase the

depth of focus.

1. Slide the aperture iris diaphragm adjustment lever. Sliding it toward "\" on the left opens the aperture and sliding it toward

" " on the right closes it. Adjust while observing an image to check the effects of adjustment on contrast and depth of

focus.

# Do not close the aperture too much for this may cause degradation in resolution and/or cause ambient light to be

insufficient.

# When the microscope is combined with the SZX-ILLC coaxial vertical illuminator, minimizing the aperture may

obscure part of the observed field of view. In this case, open the aperture to an intermediate position.

# Minimizing the aperture and setting zoom magnification high tends to make ambient light insufficient.
