You should use a reinforced concrete mould sprayed with laquer and then apply vaseline. Then, use this large mould leveled properly and pour clear casting resin onto the vaseline thin layer dome hemisphere. So you get a large lens that can cost thousands of dollars. The concrete cast can be hemisphered perfectly using a curved edge half circle made from MDF. When spinning around this half circle into the thick concrete you will get a perfect dome hole. Leave to dry 2 hours and come with sand paper rubber disc. Get it almost glossy. Then apply liquid adhesive to make it glossy with a roller. Add furniture laquer. And job done. Keep it clean and use a brush with some clear vaseline or vegetable oil when casting a new lens. Let the casting resin to dry till next day, then use a large wool to turn the heavy block upside down slowly. In this way you get the perfect lens. Do not forget to use a tiny pin and gas torch to boil the few air bubbles when pouring resin. Follow my advice and you have your own most expensive lenses.

Thanks. Acrylic is apparently naturally UV degradation resistant. I'm thinking about clear casting a protective/concentrator window covering for a small solar panel integrated into a product I'm designing. Your work through of the various gotcha's and techniques was very helpful. Thanks.

Awesome. Been waiting for a way to make or buy custom lenses for my valve index. I hate fresnel lenses.

E se no caso eu não tiver uma câmara de pressurização, vai funcionar mesmo assim?

amazing cast! I'm impressed how clear it came out to be does the clear outcome depends on the mold or type of resin used?

try molten glass/plastic spin casting, lower melting temperature for plastic, liquid form essential

Sut when you let it dry, how much gravity deforms it ? In 7 days or do you've a process of solving it

Hello thanks for the cool video. How many times can I use this silicon mold without ending up withe a cloudy resin look? would the silicon mold`s surface roughen up over time? Thanks

How do you make the molds?

Could you please tell me how your cast resin did not stick into your silicone mold? Did you spray some sort of a release agent? (That did not interfere with the glossy finish) thanks
@daniel777L Жыл бұрын
also curious about this - does anyone know? i dont think he mentions so i assume no release agent?

i would agree, no release agent.@@daniel777L

You should REALLY consider attempting to make lenses for the HTC Vive Pro 2!!! $$$$$$$$$

Whats the use of pressure chamber
@yanwolff3368Ай бұрын
I guess so that small bubbles trapped in the resin gets out ;)

Didn’t show the most important part. How to make the mold.

Probably bought a high quality lens, but leaving that part out was pretty weird.

Grinding and polishing is not that difficult and it produces clear optically near perfect results, all this ‘lens’ moulding is simply a waste of effort.
@prakashborole94999 ай бұрын
For mass production of lenses grinding and polishing is not preferred therefore moulded lenses fast and economical
