Was hoping someone would be able to help out....
I have a scope that I have to course adjust whenever going from 4x to 10x. Its a Nikon and I've adjusted the aperture and such. Anyone have any suggestions? Thanks.

I've noticed the same thing when I use a microscope that doesn't have the same types of objectives. The working distance of different objectives, even if the same name brand, is different.

my brand new Nikon does the same thing and it is annoying as hell

i'm going to have the service guy go over it with me next time he's around so i can learn how to fix it myself. it seems like such an inconsequential thing but it's so aggravating

I have a different problem with mine - the second head (for the observer) you can't converge the views from each eyepiece (so you have to look with one eye) - there is no binocular vision. It's very strange. It's like how I felt looking through a microscope for the first time, before my eyes figured out how to converge the images.

I don't know how to answer the original question - whenever I had that problem it turned out one of the objectives wasn't screwed in tightly enough. But you probably tried that.

That sounds like a problem of collimation in the second headpiece, at least according to what a microscope technician told me. He said that if the headpiece gets bumped or dropped, the prisms and mirrors can get out of place and give you a headache trying to focus the two images at once. So I guess if you switched the headpiece it should diagnose/solve the problem perhaps.

It sounds like your microscope isn't parfocal. Just mention that to the person that cleans / adjusts the scopes. A couple twists of the fine focus should be the most you need to focus between objectives.

I've noticed this is a common problem in high use scopes, such as the multi-head. This is because there are so many people that fiddle w/ it, particular clinicians.

ugg...thanks for the responses. The only thing I miss about residency is that I had a scope that didn't do this 😛

Ok I got some help from Barber Optics. It had to do with my eye piece adjustments were all the way in. Was they were pulled out and adjusted, now there is no problem.
Thanks Barber.
