In this case, parfocality assumes that the correct length of microscope tube is
used (e.g. objectives designed for a 160 mm tube, as a rule, will not be parfocal if
used on a microscope with a 220 mm tube). Parfocality is relevant to small–
subject ...

At this point, the parfocality adjustment sleeve is a temporary sleeve with
clearance holes to allow access to these screws. After the image is corrected, the
screws are securely tightened. The temporary sleeve is removed and the final
sleeve is ...

Mounting Optics in Optical Instruments
The parfocality adjustment sleeve is adjusted until the image is located at the
standard distance from shoulder -A- on the main barrel. All lenses adjusted in this
manner are "parfocalized," i.e., they have a common distance from flange to
image ...

Parfocality means that if an image is focused at 40×, you should be able to switch
to 4× and still be in focus. It is not the same as Köhler illumination. You can
achieve parfocality only on a microscope with two adjustable eyepieces; it is most
...

so that there is no need to refocus after changing the objectives or the eyepieces
except for minor adjustment of the fine focusing knob. The optical–mechanical ...

Professional-grade microscopes provide adjustments for both parfocality and
parcentrality, but student- and hobbyist-grade microscopes are set at the factory
and cannot be adjusted by the user. That means it's important to check these ...
