How you can Take away Fungus Between Glued Digital camera Lens Components


I just lately had a nasty case of fungus in a Sony package lens. The fungus was between the 2 outermost lenses which can be assembled collectively in a glued plastic case.

I positioned it in a cleaned vacuum field with sufficient rubbing alcohol to submerge it — I really needed to tilt the field to cowl every part, so I ought to have added extra.

I first cleaned every part very totally.

I sucked all of the air out of the container and watched small bubbles go away the lens.

I then let air again in. Ensure that the lens parts are totally coated with alcohol in order that it will possibly seep in.

Alcohol between the lenses:

Now empty the field, put the lens again, and suck the air out. It virtually all got here out within the first go, however it’s possible you’ll must experiment with the orientation of the lens as a result of the leaking gap must be under the alcohol.

The final droplet wouldn’t come out with suction.

Now, it is a essential step. When you simply let the alcohol evaporate, it will possibly go away a dried-out mark.

So right here’s what you are able to do: swing the lens in your arm in order that the alcohol creeps to the sting after which go away the lens to dry upright, standing on the spot the place the droplet went in order that it stays down there on the lowest level.

Voila! A hard and fast lens!

The stuff that’s seen on the outer ring is all that was left from the alcohol residue drying by itself. There’s no haze or any remnant in any respect on the remainder of the lens.

After this preliminary try, I repeated the method a second time and ended up with a lens with completely no residue in any respect.
