MICROSCOPE CARE 101
From Nebraska Scientific
(Go to our website: Click here)
We encourage the proper care of your microscope. The following tips may be helpful.
Microscope Care 101:
1. Always
carry with two hands - one on the arm, one on the base.
2. The
eyepiece, also called the ocular, is where you look through. Many microscopes may have a pointer
inside. This pointer, also called a
micrometer or a reticule, may have a tiny ruler on it for measuring. Do not remove the eyepiece as dust can get
into the tube of the microscope.
3. The
stage is the platform where the microscope slide will rest. This microscope stage will usually have stage
clips to hold the slide in place. More
advanced microscopes may have a mechanical stage - a device with turning knobs
that will move the stage for you. Keep
the stage clean. Remove any spills,
liquids or debris right away.
4. Under
the microscope stage is usually a rotating diaphragm. The disk diaphragm controls the amount of
light coming from the bottom light up through the slide. The larger the hole, the more light that will
pass. This makes the image
brighter. Turn the diaphragm to a
smaller hole if the image is too bright.
The more advance microscopes may have an ABBE condenser, a device that
controls and focuses the incoming light with more precision than a diaphragm.
5. When
cleaning your microscope, use only lens paper.
Do NOT clean your microscope with a Kleenex, paper towel, your shirt
sleeve, etc. The eyepiece and the
objectives should be cleaned before and after each use.
6. Your
microscope will have one or two focusing knobs.
The larger knob is the coarse focus;
it does a larger range of focus.
The smaller, fine focus knob, will fine tune your focusing. Always start with the coarse focus, and then
proceed to the fine focus. Once you have
focus, changing to different magnifications (changing objectives) should only
require adjusting the fine focus.
7. When
you first put the slide under the microscope, start with the lowest/smallest
objective. Objectives are the 3 or 4
devices that will change your magnification.
These usually will rotate on a turret.
Once you have the image in focus using the lowest setting, then move to
the next objective. You should not skip
objectives. Proceed in order until you
are at the magnification desired.
