I was thinking about Radiant Cooling but wondered if we could use both the cooling and heating aspects. Is it feasible to create a film that transmits 8-10µm IR with minimal loss while converting the normally scattered radiant dispersal into a perpendicular direction to focus the energy for transfer to a working fluid? Goal is to utilize both cooling and heating effects, not emit to space. For context, at 60°F with 0.9 emissivity and no re-absorption, it would take approximately 8.27 square meters of radiant surface area to achieve 10,000 BTU/hr (2.93 kW) of cooling. I might be way off here, but it seemed worth asking!
Wow, nice video man! I'm building a high vacuum chamber for aluminizing telescope mirrors and I would also like to make AR coatings for other stuff like old lenses and home made lenses. Do you think that I can achieve that with only evaporation boats? Like, putting all that stuff in evaporation boats that you have in crucible? Is all that material expensive? Do you have any sugestions where should I start? Your video is very enlightening because there is no many info on the subject.. Is there other method to achieve good AR coatings? I'm not very interested in durability of a coating because nobody usualy touches the lenses, and they are cleaned very rarely, but I would like them to work good... Thanks man!
Im no process engineer, but do know our machines... they use a very high voltage EB gun that forms a beam of electricity to burn the materials. I don't think just a boat with heat would be able to evaporate the metals in order to deposit them. There is a form of coating called sputter coating.. doesn't use as strong of a vacuum, and uses targets to evaporate the metals.....not very familiar with the process but it might be easier to build a sputter machine... You also may just buy a sputter machine for a reenable price there are a lot out there and are not very big
Thanks for the video. Would be great a video about anti-reflective testing.
I can plan for a video in the future

thanks for the information much appreciated . cheers from ARGENTINA
Thank you! This information has been so difficult to find, trying to build my own camera lenses
Is the third source pulsed laser deposition
Is there any lens protector with AR Lens for iPhone? I would def need one to use it at night.
Very informative, much appreciated.
Crucibles on the ebc 900 have 12 pockets for more chemicals to be added. Didnt see Zarkonium?
This is the Best explanation tks
how can I send u my lenses to you for recovering? do u service camera lenses?
I guess the sector won’t hold the ring 😂 9:58

@@mhopticallabs4616 yes, I will make make magnetron for sputtering, I already made one for a friend. Thanks anyway! :)
I'm on my way to have you make my glasses.....
Made me confused. Hard Surface and Hard Coating. So how does len create Hard Surface?
Anybody notice that the guy in the video doesnt have AR on his lenses? lol
Sometimes I get caught up making sure everyone else’s lenses are perfect that the quality of my own slips haha…. The situation has been fixed l! 🤫
haha, im trying to say the same thing. but there is a white color coating tho.
Does anybody see the irony? He's talking about AR coatings while wearing uncoated glasses lmao 🤣
Recommends that everyone get AR coatings on their glasses...........well except for him. His glasses are uncoated.
