4.9 Field Diaphragm Centering
BA310Met-H Microscope field of view is pre-focusing; clear diaphragm image can be obtained after
the specimen is in focus.
Adjust the aperture diaphragm until aperture diaphragm is 2/3 of field then center the aperture
diaphragm via the knurled knob on the top of EPI illuminator.
Set the aperture diaphragm slightly bigger than the field of view by turning the adjustment wheel.
