Routine Cleaning & Care of your ocular eyepieces and objectives of a microscope:


You will need the following items:

Air Duster (Compressed Air)
Q-tips
Windex, lens cleaner, or rubbing alcohol
Terra cloth


Ocular eyepieces:
Make sure the lens or the cap of the housing of the eyepiece is not loose. If it is loose, carefully finger tighten the housing part of the lens in clockwise motion. You must first use air duster to blow away any loose debris that could be on the exterior lenses. Apply lens cleaner on a Q-tip, then clean the exterior surface of the lens in a circular motion from the center to the outer edges, then take the other end of the Q-tip of the dry side to wipe off the applied lens cleaner on the lens in a circular motion until wiped clean and free of residue. Never attempt to unscrew and clean the internal lens from the housing as it is easy to lose or damage other lenses inside the eyepiece. Only a an authorized microscope service technician should carry out this task if there is debris inside the internal lenses. Should you ever get oil on the exterior lens piece, carefully use a terra cloth to wipe it off, and use Q-tip to clean the lens. If you use Q-tip before using a terra cloth, it will only smear the oil on the lens and will not come clean. Never use a paper towel or Kleenex to clean with as it will scratch the lenses.

Objectives:
4x objectives contain only one lens that rarely gets dirty as it has more working distance compared to other objectives and most of them have a cap with a pinhole just large enough to see the field of view. But if you find any loose debris, simply blow it out with air duster, and clean the lens with Q-tip if necessary. 10x , 40x, and 100x oil objectives have a few internal lenses that are bonded with a seal to keep them together to give you the required magnification. Should the 10x or 40x objectives ever get dirty, unscrew the objective from the turret and be careful not to loose any par focal rings that may or may not be with that objective (par focal rings are sometimes put in place by microscope service technicians to keep that objective par focaled so it will remain in focus with other objectives without needing to use your fine focus adjustment as much and increase your productivity), if you find a par focal ring make sure it stays with that objective, apply Q-tip with lens cleaner only to the exterior lens, then wipe clean with dry side of Q-tip. If still not clean, terra cloth may be used to wipe off any left over residue or oil that may still remain on the exterior lens and is safe to use on glass lenses. Then on 10x objectives using the naked eye, look through the screw end of the objective that screws to the turret by holding the objective up to a light source (preferably fluorescent lighting) from the ceiling in the room looking through the whole objective to make sure lens is free of any debris. Should you notice any residue, droplets from cleaning solution, or a bubble inside the internal lenses chances are the seal that binds the internal lenses together is defective and you would have to replace the whole objective with a new one for optimal performance especially if the image is still hazy, blurry, or unclear in the field of view after screwing on the objective to the turret. With 40x and 100x oil objectives repeat the same procedure, except you would need a magnifying glass to look through the objective through the screw end while holding objective up to the light source.

Remember, only the 100x (oil immersion) objective uses oil. If you must return to a lower magnification to refocus, remove the oil from the slide first. DO NOT get oil on any of the other objectives; the oil will ruin them, and you will not be able to focus on those powers. This will render the microscope inoperable, as this can lead to irreparable damage. Should the 40x objective ever come in contact with oil, immediately wipe if off with a Terra cloth (Kim-Wipes are not recommended on 40x objectives) , and then clean the exterior lens with lens cleaner using a Q-tip. You may use Kim-Wipes on 100x oil objective to remove the oil, but is not always effective. Alternatively, a Terra cloth works best if you still have oil remaining on the lens. In the case there’s dried up oil on the lower objectives and lens cleaner doesn’t resolve the problem, you must contact a microscope service technician who would be able to remove the caked on oil or other debris on the lens with a highly concentrated solution and then properly clean it for you.
