I took this apart and got a 26×45 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 following 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.
Great repurposing of materials in lieu of landfill. Will this system work in the winter as the duration of daylight is limited for prospective outdoor cooking? Is there going to be a stone/fireproof base to maximize the solar cooking potential?

upper michigan may make for difficult winter solaring for stuff. but we will play around with it. next summer i hope to build a solar oven to shine my focused light into and bake some bread and perhaps a chicken or roast. want to make the fresnel lens separate from the oven so it can be multi-purpose as a laser 🙂
