With a 75mm diameter and a 200mm focal length, this reversible mirror allows students to explore both concave and convex imaging effects, making it an essential addition to any science classroom. ## Description The Ajax Scientific Concave/Convex Mirror is a reversible mirror for demonstrating reflection and refraction to students. Its outward curved surface forms an image of the reflected object that is slightly distorted and smaller than actual size, and its inward curved surface forms an image of the reflected object that is upside down when past the focal point and magnified and right-side up before the focal point. Each surface has a metallized coating. The mirror has a 200mm focal length and is 75mm in diameter. Mirrors are used in scientific experiments and classroom demonstrations to explore optical principles and effects. Science education products incorporate applied math and science principles into classroom and homeschool-based projects. Teachers in pre-K, elementary, and secondary classrooms use science education kits and products alongside science, technology, engineering, and math (STEM) curriculum to demonstrate STEM concepts and real-world applications through hands-on activities. Science education projects include a broad range of activities, such as practical experiments in engineering, aeronautics, robotics, energy, chemistry, physics, biology, and geology.Ajax Scientific distributes scientific equipment, supplies, and instruments for industrial, research, and educational applications. The company, founded in 1984, is headquartered in Toronto, ON, Canada. ## Features - Reversible concave and convex spherical mirror for demonstrating optical principles and effects for students - Outward curved surface forms an image of the reflected object that is slightly distorted and smaller than actual size - Inward curved surface forms an image of the reflected object that is upside down when past the focal point and magnified and right-side up before the focal point - Focal length is 200mm - Mirror is 75mm in diameter ## Images ![Ajax Scientific - LI070-0020 Concave/Convex Mirror, 75mm Diameter, 200mm Focal Length - Image 1](https://m.media-amazon.com/images/I/51Etk8z-a5L.jpg) ## Customer Reviews ### ⭐⭐ Really small and not worth the price *by M***N on Reviewed in the United States on January 31, 2016* There was nothing really wrong with this mirror except it was way smaller than I expected. I paid over $9.00 for it and it was like a makeup compact size. Nothing great about it. One side you can see things bigger (concave) and the other side not. So it is definitely over-priced for this size. If they are going to charge so much for it, it would be nice if they could at least add in some interesting science experiments you could do with it. ### ⭐⭐⭐⭐⭐ Five Stars *by B***B on Reviewed in the United States on March 1, 2015* good --- ## 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.vn/products/10866613-ajax-scientific-li070-0020-concave-convex-mirror-75mm-diameter-200mm](https://www.desertcart.vn/products/10866613-ajax-scientific-li070-0020-concave-convex-mirror-75mm-diameter-200mm) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-19*
