Re: Microscope for engine oil analysis

I visited my father in law this weekend and turns out he had a microscope to borrow me: http://www.paralux.fr/donnees/documents/produits/60-6113-9/PDF-en-60-6113-9.pdf Very simple(mechanics feel really solid and precise) but it's good enough to see the amount of particles in the oil (40x objective 1...

Re: Microscope for engine oil analysis

From my understanding you could just put a drop on a glass slide and put a coverglass on top to spread it. You are looking for particles in the size of roughly 5-15um (some larger, some smaller) which are suspended in the oil. See if you can take a picture where they are visible. The soot (which mak...

Re: Microscope for engine oil analysis

Wow, that is interesting.

Can you maybe pull some oil from a dip stick and see if it will work for my purpose?

Re: Microscope for engine oil analysis

Thanks for your help, I'm starting to grasp a few things. So, after some hunting online I found that the Olympus system have plenty of stuff available. I feel that if I'm looking for parts(in the future) this system would be the easiest to live with, correct? Two question about objectives. The 'S' i...

Re: Microscope for engine oil analysis

I live in France. For second hand I'm looking at ebay europe or the national leboncoin.fr. If you can point me to a good setup(or idea of that) in the sub 500€ it would be super. I kind of need a starting point what to look for(and what to avoid). I don't mind that stuff is old per se but I do mind ...

Re: Microscope for engine oil analysis

So, your saying the optics are not up for the job? Then I will continue looking for something else. Is there any information online which optics are good/bad or reviews etc? I'm new to microscope equipment so if you can point me in the right direction (like who produces good optics....or what indica...

Re: Microscope for engine oil analysis

This is my idea right now.. There is an CX23 for sale not far from me. I like the fact that it's new in box, so it will likely give me very little issues. From a point of just finding and counting particles I think transmitted light would work best as this will give me black dots on a bright backgro...

Re: Microscope for engine oil analysis

In addition. I'm planning to have a good idea of the number of solid particles(and their size/shape) and see how reduction of this affects the oil analysis. Among other things I would like to see how clean new oil is and the result after filtering 1,2,3,4 etc times.....testing different filtering t...

Re: Microscope for engine oil analysis

Could this fit my needs? It's a BH2 with what I believe is a reflective light source.

Re: Microscope for engine oil analysis

Thanks.

Correct me if I'm wrong but all the microscopes I mentioned above are Transmitted Light Microscope?

Another question: To be able to see details of a 1um particle the optics need to have good resolution. Is the 1980's optics good enough or should I aim for newer?

Microscope for engine oil analysis

Good day, I'm a complete beginner in microscopy and need some help. I'm embarking on a project to analyse engine oil for wear particles. The particles are suspended in engine oil in the size from 1um and up. I need to be able to see if they are round/flat and maybe color(copper/brass/steel etc). My ...
