Re: Your earliest memories and experiences with microscopes?
My very earliest memories are of what was really a toy microscope given to me as a Christmas present almost 70 years ago. It gave very poor images but sparked my interest. Then a few years later I came across a beautiful microscope made by R Winkel of Gottingen in 1923. The shop owner agreed to let ...

Laminar flow equipment
The subject of tissue culture intrigues me and I'm contemplating buying / making a laminar flow hood or cabinet. Does anyone have any experience in this field?
Realistically I would only be interested in UK based suppliers. I'm pretty experienced in a wide range of DIY procedures.

Inverted microscope viewing
I've just acquired a Leitz Diavert microscope and am just about to make slides appropriate for the viewing requirements. I intend cutting 12 mm holes in standard slides and gluing a cover slip in place. Has anyone done this? Is there anything I should beware of other than ensuring a good seal all ro...

Re: Revolving nose piece

Re: Revolving nose piece
My concern arises from being unable to achieve Kohler illumination. I'm finding it impossible to centre the field diaphragm with the condenser centering screws. There's always a a dark crescent.

Is it possible for the nose piece, and therefore the objectives to slip out of alignment with the rest of the optics. My microscope is a Leitz Wetzlar Dialux?

Thanks apochronaut for your help.

Re: Phase eyepiece/telescope
Yes the Olympus has a worm screw for focusing and I thought, as you say, that maybe there's not enough latitude in the movement. I did try lifting it slowly out of the tube as I continued to look through it but no joy. I'd be very grateful if you could try on the 170 objectives. If successful I'd be...

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.
