Fresnel Lens

I got to play with my Fresnel Lens today after work. I ended up burning some plastic, paper, wood, corn stalks and also my hand, leg and almost the dog.
I still need to put it in a frame to get it's full potential, but it was still fun.


  1. You should not play with such toys. You are dangerous. hehehehhehehe

  2. I got several 8.5 x 11 lenses the other day and burned a hole in my buddie's pants' leg before I even knew what I was doing. We were able to get the small ones up to about 375 F. Pretty awesome. Don't melt a hole through the planet with that thing...

  3. Thanks for the comments.
    SFG - I agree but it is so much fun.

    Hillbilly - It is easy to do. I have to get this one in a frame before I can see what temperatures it will reach.
