Hello from Warwickshire

[Tiny-James]

Just a quick hello
I live in Warwickshire UK.
I bought a second hand stereo Microscope for watch repair's, I'm 55 years young and just getting in to watch repair's with the aid of a microscope


The microscope has some fungus on the eye piece's but I not that bothered about this.

I think the microscope is a Brunel MX 2 it has a Brunel address sticker on the bottom for Bristol UK

Hi James,
I'm supposed to be an horologist in Devon,still have the tools anyway.
Good luck with watches, anything that makes it easier on the eyes has to be worth a go.
Zeiss lens cleaner spray is not expensive and works well on fungus,actually does what it says.

[Tiny-James]

I have lens wipes, would these work @Phil Brown

[Tiny-James]

sorry woops
I also have Ammonia based sonic cleaning fluid Elma 1:19 red

will the above work

If it is a modern scope it's likely IPA or denatured alcohol would be ok for most residue.
Fungus can look like the coating is damaged after ineffective cleaning with IPA or denatured alcohol.
Another good way to get a bargain scope or parts from someone without lens cleaning solution.
I paid less than £5 Amazon for the Zeiss spray if I remember correctly.
Good luck with whichever way you choose.

thank you Phill

Check out this literature from Zeiss.
Entitled "The Clean Microscope" by Dr. Michael Zolfell

https://www.zeiss.com/content/dam/Micro ... -zeiss.pdf

It covers optical glass properties, cleaning agents with explanations, and procedures.
A list of suppliers and recipes.

Carl Zeiss optical cleaning solution;

85% n-hexane (ACS or analytical grade)
15% Isopropyl alcohol 95% +

Acetone is recommended for cover slips only.

Many solvents can ruin the vintage enamel coatings.
5-10 drops of liquid dish soap in 10 ml deionized water
is a general surface degreaser and rinses in water
Ionized water can leave dissolved metal residues on glass that will not be removable.
Some such spots or stains are actually etched areas and we all know you cant wipe away a hole.
To avoid Inevitable corrosion avoid acidic substances around microscopes.

It's always good to practice on a non critical low cost coated lens in a good light.
Some of the greases used to dampen optics can be resilient around the edges.
Quantity control isn't always there with the factory sticky stuff.
If I bought a chinese watch I'd need to manage my expectations also.
