Re: Options on a Nikon Optiphot stand
...I need some help/ideas please with adding an adhoc bottom lighting option with condenser to a Nikon Optiphot Epi Stand. Similar like this ? (I used it for the different purpose). You could use without heat sink, by attaching directly to the frame (which will work as a heat sink) COB used - https...

Re: Onion
Very interesting article from Quekett (thanks to jmp from Microbehunter), which confirms some my findings. It will answer John's (Dolmadis) question also. Cut my acrylic plate using blade saw and designed new fixture. Appears it was wasted time and efforts - 12mm thick plate was too thick - trying t...

Yes, and two polarisersrjlittlefield wrote: ↑Mon Mar 29, 2021 7:03 pmThanks for the additional info!
So, one stressed plate below the condenser, and the other above the objective?

Re: Onion
Saul, the Sanderson prism stuff is totally new to me. I've had a quick read through the paper you referenced, but I have to confess that I'm still unclear on how to adapt the technique for use with macro/micro optics. Can you provide some more information about that? What did you have to do, to mak...

Re: Dimmable LED/flash microscope illuminator
LED version only, but can be upgraded to the direct flash plus LED version also. Picture shows simple heatsink, but unit can be used with much more powerful LEDs using bigger heatsinks.

Re: Dimmable LED/flash microscope illuminator
Finalized version with heatsink which can handle approx. 22w (continuous duty). This design allows to use more powerful LEDs also (there is no heat stress on the 3D printed body) with bigger heatsink (or adding additional surfaces to the existing one (big plus of the T-Slot extrusion)). That all all...

Re: Even DF illumination for 4x objective
Anyone got any advice on how to get great DF on a 4X objective that evenly illuminates the whole field? I have a Nikon Optiphot, but I have heard that some Olympus condensers are easy to adapt to the Nikon dovetail for the substage condenser, and that the olympus condensers have a filter tray for a...
