Fresnel Lens

Fresnel Lens

7 total reviews

    Item #133


    Lenses are used to focus light. But on larger scales, conventional lenses can become too massive. The Fresnel lens allows for a lens of large aperture and short focal length useful for efficient magnification and concentration on any scale. Physicist Augustin Jean Fresnel designed its clever surface which is divided into concentric ridges. By layering these ridges to be on the same curvature, it becomes a lightweight alternative for most projects. 

    These lenses are not unlike a reverse telescope. Instead of bringing in light from far away, these lenses are capable of concentrating light to a narrow point to reach great distances. 

    Used in lighthouses to bring ships to safety through their concentrated beam of light, they have been called "the invention that saved a million ships".

      Perfect and handy

      This little lens is perfect for quick, satisfying glances closer at the curios and specimens I’ve collected on my desk. Sturdy enough and still flexible, it’s a little larger than a standard index card and is worth it— especially while it’s still on sale.

      WE TAKE SCIENCE SERIOUSLY

      You deserve better than craft store science products. And we think learning is more impactful when you're holding a tangible piece of what you're learning about. That's why Stemcell exists.

      We're dedicated to providing the best scientific products available—whether they're fragments of scientific importance, experimental activities, or just interesting things that scratch your curiosity itch.

      With every new product launch, our list of new ideas gets longer rather than shorter. So check in often for our latest projects, and thanks for being a part of our endeavor to make the world a smarter place to live.

      Believe in yourself; for everything else, there's science.
