Re: Focus mechanism of Leitz Wetzlar Dialux

Yes I've been trying on BF but am unable to focus and centre the image of the field diaphragm. Maybe the condenser itself needs an overhaul. The centering screws are very tight.

Re: Focus mechanism of Leitz Wetzlar Dialux

Thank you apochronaut. I've left it out again without issue.....so far.
Now I'm struggling to set up Kohler with the 402a phase condenser. This too may need an overhaul. I'll check out the site for info on doing this.

Re: Focus mechanism of Leitz Wetzlar Dialux

When I look further back I think the subject began with a post in photomacrography.net~amateurmicroscopy.net
by steveminchington. The post heading was Leitz Dialux stand - rebuild photos added. It was taken further by gpmathews.
Mind you this was 12th Mar 2017.

Focus mechanism of Leitz Wetzlar Dialux

Hi. I am freeing up the focusing mechanism of this microscope and so far so good, using a series of excellent photos uploaded by gpmathews. Can anyone clarify what the Bottom Stop Pall does please? The tiny hair - like spring has sprung and I'm struggling to see how it is goes back. This happened on...

This is fodder for another forum really, It's too far removed from microscopy. So as they say " I'm out "

Are you talking about individual consciousness or some mystical universal consciousness. The former being at the forefront of research in neuroscience, whereas the latter is in the domain of the philosopher?

Re: DIC with Leitz Wetzlar Dialux

Further to the post citing Thilo Himmel, I've been in touch with them and just today received an email saying that they only trade within EU because of costs. So my hunt for a 402a Leitz condenser goes on.

Re: DIC with Leitz Wetzlar Dialux

Thanks Tony but I have now got a x25 phase objective. I'm not sure what the import costs are but from what I hear it's not cheap.
Am I right in saying that you have a 420a condenser too?

Re: DIC with Leitz Wetzlar Dialux

This is the thing I don't understand....I thought that one of the key components for DIC was a second prism between the objectives and the analyser. Unless each objective has this prism within it?

Leitz Wetzlar condenser ICT 1268

Can this condenser be used for phase contrast only without needing to change anything else on the microscope apart from the objectives. On a Google search it seams to be capable of DIC as well but this needs additional parts. Thanks

X40 oil objectives

Hi. I read recently about the improvement one gets when using an oil objective, in terms of image quality.
Can you use oil with a x40 objective that doesn't have ' oil written on it?
Thanks for all fascinating posts.
