No more eye strain and headaches thanks to the larger, clear print these premium magnifiers deliver. Easy to Use - Simply place the magnifier about 3 inches from the object you're looking at.

Lots of campers use these as natural fire starters. Just magnify the rays of the sun. Use your imagination for endless DIY projects that are fun, educational, and useful. Review: Works great as a firestarter. Ok as a magnifier. - Main reason I got it. In 71 degree weather, it lights up a chip pile in a flash. I will be using it to make a solar still for water and so far it looks promising with one more added. Nice add to the trailer for starting fires. You won't be disappointed in that area but as a magnifier, it is a little less than desirable. It is ok on print for instructions, books but finer print like on a USB charger, (what I tested it on) it isn't clear enough to make out the info. Still worth the money to me. Review: Thinner, but works - UPDATE: Sunny, breezy day. Got it to focus. Burned paper (ignited). Burned stubborn pine twig (surprised to see a mini torch). Even through the protective plastic wrapper. Can't truly complain. Worked like the picture. ORIGINAL REVIEW: The fellow burning something in the picture is probably having to hold the lens very carefully. It's flexible. Will update after I've had enough sun to play with it a bit. I didn't deduct more stars because it's basically a page magnifier. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00IITFX02 | | Are Batteries Required | No | | Batteries Required? | No | | Best Sellers Rank | #76,576 in Health & Household ( See Top 100 in Health & Household ) #176 in Magnifiers | | Brand | Cz Garden Supply | | Brand Name | Cz Garden Supply | | Color | 1pack | | Customer Reviews | 4.5 out of 5 stars 916 Reviews | | Global Trade Identification Number | 00805731900243 | | Handle Material | Pvc | | Item Dimensions L x W | 11.75"L x 8.3"W | | Item Weight | 1.76 ounces | | Lens Material | Polyvinyl Chloride (PVC) | | Magnification Strength | 4 x | | Manufacturer | Cz Garden Supply | | Manufacturer Part Number | CzFLA4-1 | | Model Number | CzFLA4-1 | | Product Dimensions | 11.75"L x 8.3"W | | UPC | 805731900243 805731900991 | | Unit Count | 1.0 Count | ## Product Details - **Batteries Required?:** No - **Brand:** Cz Garden Supply - **Color:** 1pack - **Item Weight:** 0.11 Pounds - **Lens Material:** Polyvinyl Chloride (PVC) ## Images ![8.3" x 11.75" LARGE 3X Fresnel Lens FULL PAGE Magnifier -- Solar Oven/DIY Projection TV PLANS (1 pack PREMIUM GRADE Large Lens) - Image 1](https://m.media-amazon.com/images/I/614tA0wbrGL.jpg) ![8.3" x 11.75" LARGE 3X Fresnel Lens FULL PAGE Magnifier -- Solar Oven/DIY Projection TV PLANS (1 pack PREMIUM GRADE Large Lens) - Image 2](https://m.media-amazon.com/images/I/61QVHcGKEjL.jpg) ![8.3" x 11.75" LARGE 3X Fresnel Lens FULL PAGE Magnifier -- Solar Oven/DIY Projection TV PLANS (1 pack PREMIUM GRADE Large Lens) - Image 3](https://m.media-amazon.com/images/I/71jgfBwuXQL.jpg) ![8.3" x 11.75" LARGE 3X Fresnel Lens FULL PAGE Magnifier -- Solar Oven/DIY Projection TV PLANS (1 pack PREMIUM GRADE Large Lens) - Image 4](https://m.media-amazon.com/images/I/61k3kGhQD-L.jpg) ![8.3" x 11.75" LARGE 3X Fresnel Lens FULL PAGE Magnifier -- Solar Oven/DIY Projection TV PLANS (1 pack PREMIUM GRADE Large Lens) - Image 5](https://m.media-amazon.com/images/I/51BwrxUX0ML.jpg) ## Available Options This product comes in different **Size** options. ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great as a firestarter.
