Lens Making in the 1600s 

This was a brilliant video, great editing, no stupid background music, etc. Nicely done.

Instead of thinking about worldly pleasures some choose to do these stuff. Helped us to be as sophisticated and advanced as we are now.

Thank you. You answered my question, and then you answered questions I wouldn't have know to ask.

That is one of the best videos I saw ever! Recreation and creation of these was fantastic way to learn the answer to "how people became so good at things?"

Thanks for sharing. I was planning to post the video explaining the same but i wasn't confidant.I was searching this methods for years. I tried your methods before your video. Grinding produces good lenses. I used slightly bigger glass piece then stuck it to a round metal bar with shellac. then rod held in drill gun chuck. made the piece round the exact size of metal (steel) rod.then removed rod from chuck. then other steel rod dimpled by using a ball bearing ball. then by using various powders i ground it. and polished it by using fine diamond paste and wood stick the diameter i made was 5 mm. It produced good lens.

Fascinating, an invention like this seems way before it’s time.

Thank you, Corning. You're a great company.

Thank you so much I've always wondered how the first microscope was created and I'm glad I found your video

BRILLIANT MAN..SUPER CREATIVE..ANTONY VAN LEEUWEENHOEK,I FOUND THIS VIDEO BEC.VSAUCE..NEED MILLIONS OF VIEWS..

So if i understand correctly, if i want to make my own lenses, and I’m not doing a production lot, i can easily make a jig and hand grind it to eventually create a spectacular magnification lens to any level of magnification i desire based on the concavity (depth) of my jig. I can make my own telescope, or crossbow scope, or microscope, or camera, or glasses, or solar concentrator, or anything with a lens. I love it, thank you! I own a large collection of Leitz, Leica lenses made from rare earth glass. It will be interesting to see how what i can make compares to one of the masters of this field. Obviously, Corning deserves kudos for their contributions to this field as well. Thanks again!

Superb video! This weekend's project will be an attempt to make the glass tube lens.

I used to go to the Corning museum of glass, i got a custom bowl there when i was 4 or 5

Great video !! Was very informative, interesting and helpful !!

I'm going to have to try and make some of these.

This is very neat, the last type of lens, I have seen it built into the glass envelopes of miniature incandescent torch lightbulbs, to focus the light from the filament into a beam.

extremely interesting, thanks

Why only this few views it deserves Millions

A glass ball with a flat on one side makes an even better, high resolution magnifying glass.

Incredible video. Do you currently have anyone experienced in recreating early optics like those shown in the video, as well as methods in use through the 18th and 19th centuries? Thank you.

Dr. Stone sent me.

WOW. Thank You and thank you algorithm.

what a brilliant man, he used a modern developement process of product design which is called design exploration and neither was he a scintist nor a designer in the early 1670s. Just WOW

1:24 how the curvature of the mold was made good enough for a lens?

Good video. Wish all of this channel where at least something like this. I won't be viewing 1hour irrelevant videos. So i won't subscribe and forget this channel in about 2-3 hours

What's the source of the flame

how do you remove the lens from the wooden stick and resin? after polishing

Thanks for sharing the most ancient microscope 🔬 of Antony Luenhok

what is he using for the heat sorce what is making it hot enought to melt glass so well

I often imagine what these men would say and think if I could transport them to the present to show the modern capability of miracles like superresolution imaging, electron and atomic force microscopy a million times more powerful than anything he could have dreamed of. The ability to see individual atoms. Then I think of what will be possible in another 300 years.

Cool, I'd love to create my telescopes and microscopes- if they can do it in the medieval ages, I and we can do it to, especially today in the 21st century, we hope, fast & pray. God bless.

Someone correct me if I’m wrong, but didn’t von Leeuwenhoek’s bequeathed microscope collection to the London Royal Society have the now mysteriously lost ‘glass blown’ lenses with it?

Thanks

sources?

Why is it upside down?

To short, more please 😢

How to.use.iy

For the blown glass lens, could the tube be filled with a liquid with the same refractive index to create a sort of fiber optic magnifier, the small end being used to examine a sample and the wider portion magnifying the view for the viewer?

Nice 👍

что это за горелка такая?что за топливо?

Nice video🥰

Thank you. What is the liquid used at 1:30?

He was the cyberpunk of his time.

Oooooooo my sweet silica gods

hi I saw your video and tried to do the second process of grinding and polishing. after grinding I also got curve of the lens but it surface became blur. I can't understand how to polish it. please give me answer in the form of reply.

The only way he could see truly microscopic objects was with glass beads. All other things were too weak.

Nearly 1000 years before this person, Alhazen did the same experiments.

Cool bro

NICE

How the hell did Leeuwenhoek see Molecules with that little bead of glass lol.

Could someone use these techniques today to make like a pancake lens an inch and a half wide

Who else is here to see how Spinoza was making a living?

spinoza brought me here

I thought they simply sent Marco Polo to China to buy some cheap chinese onea.

aung cough san
