DO NOT ATTEMPT TO CLEAN OPTICAL SURFACES OF DIRT AND DUST UNLESS
PERFORMANCE IS AFFECTED
Microscopes can get pretty dirty after
just a few hours of hard work. Keeping your instrument clean is
one way of prolonging the life of the microscope and its parts.
The following tips may help you keep your microscope happy and productive
throughout its lifetime:
Cautions
1) Avoid sharp knocking or jarring of your
instrument. When moving your microscope, firmly grasp the limb or
arm and cradle the bottom with your arm. Gently move the scope taking
care not to bump or jar the instrument which can damage it internally.
2) Avoid the following conditions: dust,
vibration, exposure to high tempuratures or direct sunlight for
prolonged periods of time.
3) Avoid getting dust, dirt or fingerprints
on lens surfaces. They will prevent clear images from your specimens.
Use your plastic cover provided with your microscope and ALWAYS
cover your instrument when not in use, even for short periods. When
storing your scope, always keep it in a place free of dust, moisture
and fungus.
Cleaning Materials
The following materials are generally accepted
by most microscope and optics suppliers:
- Lint-free Cotton Swabs on wooden sticks
- Mild Soap or Detergent that is fragrance
and color free
- Powder-free latex or plastic gloves
- Reagent or medical grade isopropyl alcohol
or reagent-grade acetone (use acetone ONLY when absolutely necessary)
Lens Cleaning
Eyepieces and objectives are the "front-line"
optics of your microscope. They are the parts that will get the
most exposure to dust, dirt, oils from fingers or eyelids and other
contaminants depending how your microscope is used.
Most dust you see on objective lenses,
mirrors, correcting plates eyepieces and filters is harmless and
rarely effects the quality of your optics or image quality whatsoever.
This dust can be left alone or simply blown off with high-quality
compressed air product that uses dry-nitrogen as its propellant.
Most compressed air products for electronics
or computers use solvents for their propellant and SHOULD NEVER
BE USED ON OPTICS. The main issue is that cheap canned air will
frost the area you are cleaning with propellant leaving behind a
light milky film that is even more difficult to wipe off or remove.
Then followed by excessive wiping will then damage the optic further
by making microscopic scratches or, at least, damaging or outright
removing the optical coating from which there is no going back.
If dry-nitrogen propelled compressed air
cannot be found, consider using a very soft cosmetic or bellows
brush sold at camera stores. Many optics suppliers also sell these
brushes and they are a good and relatively inexpensive investment.
For removing smears or oil from optics
use a pure grade of isopropyl alcohol with lint-free cotton swabs.
Do not use lens tissues made for eyeglasses. They tend to use silica
powder and other ingredients that could potentially scratch or harm
your optics.
Many optics suppliers like Edmund Scientific
offer cleaning kits with lens cleaning solution, bellows brush,
lint-free wipes and lint-free cotton swabs meant especially for
optics cleaning.
Cleaning Directions
- Gently blow away the course dirt particles
with a bellows brush.
- Using a lint-free cotton swab, dip the
end into your cleaning solution; alcohol,etc.
- Shake off excess fluid from the swab.
- Using the cotton end of the stick, start
at the center of the lens using a circular motion and work your
way to the outer edge.
- Gently wipe off any excess liquid with
another dry lint-free swab.
- Using another lint-free swab, gently
wipe off any residue on the glass.
- Use the bellows brush to blow off any
residual lint, dust or debris.
- Check the cleaned part with a jewelers
loupe looking for any uncleaned spots.
- If not clean, repeat procedure again
always using fresh new lint-free swabs.
- If the object still cannot come clean,
consider professional help or simply replacing the optic.
Cleaning Stages and Stage Plates
Stages can get pretty messy from examining
biological or industrial specimens. Using just a lint free soft
cloth with a mild soapy solution works best. Don't use an overly
wet cloth as moisture may seep into the stand which may have electronics
inside. It's always best to unplug equipment before attempting to
make repairs or to perform cleaning. Do not use alcohol, acetone
or other solvents on your instrument as they may cause damage to
painted surfaces.
For glass stage plates, we recommend using
mild soapy water and using your bare hands. Have a soft paper or
cloth towel to set the glass on after you've washed and rinsed your
glass. Carefully dry the glass. It can be a bit damp and let the
air dry the glass completely. If you used distilled water, the glass
will dry without leaving mineral deposits. Then, by holding the
glass by the edges, drop the glass back into the stage and tighten
down the locking thumbscrew.
Don'ts
- Do not use any aerosol spray product,
no matter who sells it or what their claims are.
- Do not use eyeglass lens tissue, toilet
paper or other paper. It DOES scratch glass !
- Do not use pre-packaged cotton balls.
Most of the time they are NOT made from cotton.
- Do not use lens cleaning solutions
marketed by resellers using their brand name. Making your own
cleaning solution can also be cheaper and more effective.
