This reproduction 5th order Fresnel was modeled after the original manufactured by Barbier and Fenestre, Paris in 1877. The 180 degree fixed lens is equipped with 180 degrees of prismatic reflectors at the rear of the lens.
As early as the 1920s, articles in the United States, Popular Astronomy and in Scientific American instructed people how to hand make Telescope lenses. So yes, earlier generations certainly were splendid, well skilled artisans! 🇺🇸 😎👍☕
Fascinating and beautiful to watch - though I was a little disappointed that it didn't show what I was hoping to see. The old light houses have a fresnel lens made from glass, and some of them are huge. I have often wondered how they were figured and ground.
Thank you!!!! This was amazing! I come from Newfoundland where so many many men on the oceans depended on the lighthouse to keep away from the rocks and to find their way safely home. My forefathers on both sides of my family and my husband's family were whalers, sealers and deep sea fishermen. Watching this video has been emotional for me . Thank you again.
Stunning! An impeccable marriage of form and function. The base is an absolute poem! Great respect to all the machinists and skilled workers and designers involved.
No matter how one looks at it, there is a great potential in that piece. This reminds me of some of the clockwork which was done at the time of this type of work. What a wonderful amalgamation of materials, human mind and craftsmanship. There are a few points one could improve, but all I am going to say, is that it has a human spirit in it and many modern items that decorate a house have not. Congratulations to the craftsman.
There are not words that express any equal to the definition of how incredible the craftsmanship displayed in such magnificent piece. i feel it's unparalleled to anything I've ever seen.
What a gorgeous display of skilled workmanship. I'm not sure if these lenses rotate but at some point a ship will see a brief, intense flash of light from the center of the lens known as a "bulls-eye".
Simply beautiful. I am so happy that people are still practising old school craftsmanship. So much knowledge could be lost without people like those involved in this project.
Imagine to construct a dozens perfect lenses in 1877 without all these computerized cutting and lathing machines calculating with nanoscale precision. All honors for Fresnel
I would love to have that as a piece of art in my house. Simply amazing! I don't think that I could come up with the right words to describe this work of art, if I did I'm sure it would be an understatement! Well done! Thanks for sharing!
Gorgeous just Gorgeous! I have a love of light houses! If I ever have the opportunity to restore one, I Definitely will come to you guys for the Fresnel Lens housing!
This was really fun to watch and I really loved the quality in which you shot everything. Could you upload a version where it's just the natural raw sounds of you working/the sounds of the machining? The music was very repetitious and distracted from the video, I thought.
This is a piece of Art! However I will ask the proverbial question that many have asked in the comments below, what would be the cost of these if they were produced in a limited release edition? What would the release numbers be, 100, 250, 500? As for the negative comments towards acrylic lenses, the choice for acrylic over glass will reduce the overall weight of this assembly and it does not affect the light output or quality as a display piece in a personal or public collection.
So we learn every day a new lesson. I was thinking that the prisma is glass. What ever, that is a fine peace of craftmanship. Very well done. It is fantastic to see what people can build.
Truly a work of art! Just watched a lighthouse documentary that showed some that idiots had shot through🤬. How could anyone bring themselves to do that? I would just stare at it in awe and appreciation for the amazing workmanship😲
Maravilloso video. Todo calza a la perfeccion extrema. No me hubiera sorprendido que el constructor hubiera vestido con traje blanco y en ambiente antipolvo
Amazingly beautiful item! I thought it would have been made of glass but I guess plastic is the way to go nowadays. And I bet it cost a pretty penny to boot!
