Proper
User Set-up for Stereozoom
1.
Set cross-line target on stage. Best results are achieved with 0.0006"
cross-line reticle of
30 mm diameter. Focus and center cross-line image at highest magnification
setting.
(If no glass cross-line is available try making your own cross-line with a very
fine pen.) It
may become obvious to you that your eyes must strain in order to focus on the
center of
the very fine cross-line. Continue with the rest of this procedure.
*
This eye strain effect may be the cause of user complaints and can be corrected
by a LASER alignment
performed at ACC’s facility.
2.
If your microscope has dual diopter adjusters (one on each eyepiece tube) they
should
both be set at the zero mark or line. If there is only one diopter adjuster,
please see line #3.
3.
Focus at highest magnification using the stand focus knob. “Best focus”
preference
should be given to the fixed eyepiece side (usually under the right eyepiece).
Do not
move the stand focus knob from here on.
4.
If you have a fixed eyepiece -- Looking through the fixed eyepiece side check focus of the cross-line target
image at lowest zoom magnification setting. The fixed eyepiece image should
still be clear. If not, the scope
needs
other adjustments.
5.
Focus the other eyepiece also at lowest magnification using the adjustable
diopter
collar under the eyepiece itself (usually under the left eyepiece). Again, do
not use
the stand focus knob. If dual diopters are available - each eyepiece should be
adjusted for best focus individually. Using a jewelers screwdriver, now set each
diopter
adjuster to its zero mark. This will ensure that you will always be able to
quickly reset
your scope to your best parfocal setting very quickly and easily even if other
people use it.
6.
Scope should now stay focused when going from high to low magnification
as long as the stand focus was set at highest magnification, and eyepieces were
focused correctly (and matched) at lowest magnification setting.
7.
Recheck by setting scope at highest magnification, focus image using the stand
knob then go to the lowest
magnification. Both images should be clear. Use this
procedure before starting your work under the microscope
at the beginning of
each day or after someone else has adjusted your microscope.
