## Description

Fresnel lenses are most often used in light gathering applications, such as condenser systems or emitter/detector setups. Fresnel lenses can also be used as magnifiers or projection lenses. These lenses are also great for enlarging fine print in books, magazines, maps, telephone directories, recipes, etc. This can really be a great and creative gift to children as a toy and those who need visual aid. This fresnel lens is also very good for experiments of gathering solar energy. Thanks to its large size, it usually can start a fire within seconds on a normal sunny day. I personally can use it to start melting an aluminum can around 45 seconds under sunshine. Try it your way to boil a bottle of water, start a camp fire, or build a water heat pipe, etc. - Link, user name & password for the 6 plans will be emailed to you.

## Questions & Answers

**Q: What is the focal length? Thank you.**
A: The groove pitch is 0.5mm. The focal length is 320mm

**Q: Cant I cut this into a smaller sizes with an exacto knife or box cutter?**
A: Wow, a bunch of wrong answers. Not only is it possible to trim the edges and use the center portion, it is even possible to cut it into sections, and each section will continue to function. The only difference is that a lens cut from a location not in the center will need to be held over to one side. If it isn't apparent what the total effect will be, just imagine that you took the lens and covered half of it with paper and tape, and then covered have of the remaining rectangular piece, so that once again you have a square section. Obviously this section has to be held to one side, and it probably wouldn't work very well for a reading lens. But you certainly could still use it to start a fire.

**Q: what is the magnification**
A: Unlike with a telescope or a microscope, a magnifying lens's magnification varies as you move closer to or farther from the object you are observing.  I can tell you that it can project the light from the sun to a point about 1/2" in diameter.  This is a concentration, compared to the size of the rectangular lens, of almost a factor of 500.  That doesn't mean that you can see somethings 500 times its size by looking through the lens.  What is means is that it has a huge amount of light gathering surface and focuses it on a very small spot.  This may not be the answer you are looking for; but I can't think of a better way of stating it.  It can ignite a fire in a second or so.

**Q: How can it be used for 'do it yourself solar cooking'?would this size be bigenough to cook?wouln't it need reflector to reflect to the bottom of pan?**
A: I have seen a fresnel lens used to cook (at burning man). They pointed the beam at a cast iron and cast iron pans are good at dispersing the heat evenly across the pan. It probably took a while for it to heat up but it was definitely working.
