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. ## Features - 2PCS/Pack square acrylic fresnel lens - Size:250*250mm, Focal length:200mm, Thickness:2mm, Material:PMMA - Visual Aid for education - Great for reading small text, DIY Solar Cooking, DIY Solar Heater, and DIY PROJECTION TV, For Scientific Research - High light transmittance, High efficiency in focusing - Lightweight, Flexible, Durable ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #728,676 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #548 in Science Classroom Optics Kits | | Customer Reviews | 4.3 out of 5 stars 6 Reviews | ## Images ![2-Pack Fresnel Lenses 250 * 250MM Focal Length 200MM Acrylic Fresnel Lens Fire Starter/Solar Oven/Scientific Research&Education/DIY Projection TV PLANS By Six Seasons - Image 1](https://m.media-amazon.com/images/I/81Iv+b6NleL.jpg) ## Questions & Answers **Q: Can it melt copper on a sunny day? Thanks!** A: Hello, the focal point of big lens can reach 1000 degrees under sunshine, but the melt temperature of copper is 1083 degrees, so i am not sure if it can melt copper, it affected by the size of lens and the condition of sunshine. You can try a bigger size such as diameter 400~500mm, we have even diameter 1000mm lens which can create 1000 degress in seconds, but the cost and freight charge is high. ## Frequently Bought Together - 2-Pack Fresnel Lenses 250 * 250MM Focal Length 200MM Acrylic Fresnel Lens Fire Starter/Solar Oven/Scientific Research&Education/DIY Projection TV PLANS By Six Seasons - 8.3" x 11.75" LARGE 3X Fresnel Lens FULL PAGE Magnifier -- Solar Oven/DIY Projection TV PLANS (1 pack PREMIUM GRADE Large Lens) - Opticlens Brand 2 Pack Full Page 3X Magnifier/Plastic Magnifying Sheet Fresnel Lens, 2 Count (Pack of 1) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/78078962-2-pack-fresnel-lenses-250-250mm-focal-length-200mm-acrylic](https://www.desertcart.tn/products/78078962-2-pack-fresnel-lenses-250-250mm-focal-length-200mm-acrylic) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-11-02*
