What is the diameter of the lense?

@MawoDuffer Ай бұрын

I’ve been looking this up. I found that the foldscope lens is 2.3 mm for 140x magnification. But it looks like 3mm might work too. There are industrial sources that sell glass spheres. I will see if they are clear enough

@rplanet_r Ай бұрын

@@MawoDuffer I made different diameters, the lens with a diameter of 2 mm is the best, I even saw red blood cells. I made these from a simple glass food jar.

It's amazing how much magnification they're able to achieve back then.

How much magnification?

Interesting that the bacteria don't evolve with their host, instead making the whole worse.

What changes when the glass bead is made bigger or smaller?

@pedrova8058 Ай бұрын

if the radius curvature change, hence focal length chance, so the magnification change (bigger radius, less mag. Smaller glass bead, mean more magnification)

the smaller the bead the higher the magnification

how much is the resolution this microscope can get? by the way this is the most awesome thing i've seem in a while!! thank you so much for sharing it!!

I feel like the phrase "O Ye of Little Faith!" fits me here, I like how this is simple and still used, but I admit that I'm having a hard time believing that it would actually allow you to see bacteria. I mean, I'm sure that you can't see all types of microorganisms, but I'm curious. I'll have to try this out and I do believe you! Its just personal curiosity, but for example would you be able to examine a sample of blood with it? And what about using a glass stir rod instead? The end result might be a bit bigger, but I'd imagine it would still work right? Thank you for posting and making this video!

@animehair05silently88 10 ай бұрын

if i remember correctly from high school, the reason a van leuuwenhoek microscope has such high magnification is because the curve of the lens is so sharp from how small a sphere it is, and the process shown here would make a *very* small sphere i think (except compared to things on the scale of what you look at with it)

Someone please listen - You just discovered the way we can change the world. With two pieces of paper and a glass sphere, mounted to your cell phone we can turn healthcare on its head, with every patient empowered to sample and deliver viable data real time! Do you realize what you've done? You have saved mankind. To wit, using your demonstrated tech, every person on Earth who has access to a camera phone can image blood and tissue samples realtime for a realtime remote diagnosis. I'm nobody who knows even less but I know what I know. I know that anyone can replicate this tech and apply it. No more high risk onsite collection, no more 'hurry up and wait' for samples to transit, subjected to analysis, etc. Please God, let them see.
