5.2.5 Adjusting the tubes and eyepieces
With the right settings, you can achieve an image which is sharply
defined over the complete magnification range without any
renewed focusing during the magnification setting.
Prerequisite þ The surgical microscope is positioned vertically above a level
object.
þ Do not wear any bifocal or progressive lenses for the
adjustment procedure and subsequent work with the
microscope. Such lenses make correct diopter setting impos-
sible and result in unsatisfactory imaging.
þ
Have writing implements ready. To permit fast setup of the
microscope, it is advisable to store the pupillary distances and
prescriptions of the different users so that they can be easily set
during system preparation.
Action 1. Look through the eyepieces.
2. Position the eyepieces at eye width using the [Interpupillary
distance] adjustment wheel so that both eyepiece images
appear as a single image.
3. Set the diopter setting on both eyepieces to "0" diopters.
4. Set the surgical microscope to the lowest magnification setting.
5. Look through the eyepieces and move the surgical microscope
to focus the image.
6. Set the microscope to the highest magnification setting and
correct the image with the focusing function until it is sharply
defined.
7. Reset the microscope to the lowest magnification setting
without changing the working distance.
