Re: DIY apodized phase plates/objectives?

Unfortunately I agree with the previous issue, if you glue an extra thick ring over the phase plate, it will destroy the phase coherence. I think that 0.1mm does not mean exactly 100,000 nm, but has an error or plus minus 10,000 nm, so you never know where the phase will be. A plate exactly 100,000...

Re: DIY apodized phase plates/objectives?

I wouldn't go out and say it's impossible but were dealing with some pretty small margins for error here. Careful gluing stuff to your phase plate as I imagine you will not get it right the first time and then you are out a perfectly good phase plate. Also, maybe reflection should be the principle ...

Re: DIY apodized phase plates/objectives?

That sounds like a phenomenal idea and might be way easier to test experimental setups with, though I currently don't have any experience nor the technical understanding to know how to install such relay system. How would one do that with finite scopes? I currently have an Olympus BH-2 with a phase ...

DIY apodized phase plates/objectives?

I'm looking into a diy solution to convert preexisting 40x 0.65 NA and 100x 1.3 (oil) phase contrast objectives into apodized ones to reduce halo artifacts and to visually enhance the resulting image. The technique itself is remarkably simple and it shouldn't be too hard to implement, but I reckon i...

Re: Complete Zeiss Standard 18 microscope with 5 objective turret for sale

Hi!
It'll probably too much for me at the moment (thanks to impulse buying microscopes and a lot of damaged parts to repair), but just out of curiosity, what would be your asking price?

What's the part on this Zeiss condenser rack?

Hi all, I've recently bought my first scope! It's a Zeiss Standard 18 in great condition (albeit a bit dusty) with a drawing tube, 1.3 NA fliptop condenser, 5x objective revolver, a full set of objectives (Planachromat 2.5/0.08 and 10/0.22; Neofluar 40/0.75 and 100/1.30 oil; Plan-Neofluar 63/0.9), a...
