Today, we will provide six tips to properly clean oil off your objective lens. Despite this, researchers and lab technicians often forget to clean their immersion oil objective lenses-and end up facing some sticky consequences. This entry was posted in Blog on by UNITRON.Objectives are precision pieces of microscope equipment, so they must be cleaned to ensure proper optical performance.

You could use other organic solvents to remove even more stubborn crud (Residual Oil Remover, pure petroleum ether, etc.), follow same procedure as in Step 4, and use sparingly! Before even trying xylol or ethyl-ether, it may be safer and more effective to send your objective to a professional for cleaning.
IMPORTANT! DO NOT SOAK THE OBJECTIVE IN THE SOLVENT as this may soften the cement securing the lens elements. The next step up in solvents would be xylol or a 1:1 mixture of ether-ethanol. Sometimes the stuck-on grime is more stubborn, such as dried-on immersion oil. Use stronger solvents (WEAR NITRILE GLOVES), or seek professional help.As discussed before, wrap lens tissue over applicator stick and dampen it (not soak) with the solvent before wiping. Avoid getting these solvents on the rubber eyeshields of eyepieces. You can also use isopropanol or ethanol diluted to 70% in distilled or deionized water. Sparkle glass cleaner has been a favorite, but dilute it 1:1 with distilled or deionized water (a.k.a. When water/breath doesn’t work, the use of alcohol or lens cleaning solution (Fig. Use alcohol or lens cleaner (WEAR NITRILE GLOVES)Īfter introducing lens tissue for some mechanical assistance in cleaning, the cleaning steps only increase in the aggressiveness of the solvent.Always wipe the glass using the same spiraling method.
Wetting the lens tissue with a little bit of water may also help. Just like breathing on your eyeglasses or a windowpane to make it fog up, you can add a warm breath to Step 2 to aid in removal of dust, debris, and some smears. Inspect the glass surface with your handy 10x magnifier and repeat the process if needed. Don’t rub the glass, rather gently wipe the glass surface in a circular pattern, starting in the center and spiraling outward (see Fig. You can also fold the lens tissue into a point. Wrap the lens tissue around a cotton-tipped applicator stick or Q-tip. It is lint-free (no added dust, and non-abrasive). Both are abrasive to optics, and facial tissue may also contain “softeners” which will add smears to the glass. Many people initially reach for Kimwipes or facial tissue. This step also avoids any physical contact with the optical surface, minimizing the potential for scratching or smearing it. A puffer or can of compressed air are ideal for this. 1)īlow off surface dust by blowing air across it. With a little practice, you’ll be able to see smears, dust and even damage to the lens. You can also use an eyepiece as a handy 10x magnifier – just remove from the microscope and look through it from the back end about 1 cm from the item you are inspecting (see Figure 2b). eyepieces and objectives) if you remove them from the microscope. It will be much easier to inspect and clean the optics (e.g. These steps increase in aggressiveness of the cleaning method so, for the best results, always start from the top and work your way down. Here are some basic guidelines for cleaning microscope optics. In a worst-case scenario, your microscope could be rendered useless. Grime on your optics reduce the resolution, create artifacts, and degrade the image.

Would you wear dirty eyeglasses or sunglasses? Just like these, microscope optics work better when they are free of dust and smears.
