Recycling TV Fresnel Lens
I took this apart and got a 26x45 spot fresnel lens.
It’s very powerful...
Brand new ones this size can cost up to $3800 for a quality one. Used they go for around $250.
The one I got is in near new quality and probably a re-sale value of about $200-300 to the right crowd.
TV companies buy in huge bulk to get the cost of fresnel lens down quite a bit but main reason tv's that use them cost so much.
I intend to frame this one in and build a solar laser to burn things and cook with. Something like these below...
These other lens came out of same tv. The first and outer layer lens is a clear plastic protective lens. The second is a fogged lens to cut any glare. The third is the fresnel lens which diffuses the projector lights to help create a quality viewing.
