A Fresnel lens replaces a traditional curved lens by adding concentric grooves to the surface of the lens, as seen below left. These grooves act as individual refracting surfaces that turn a light source into parallel rays that can be seen for very long distances, as in the case of the lighthouse. In our demo we take the light in the opposite direction. We face those grooves toward the sun, and its incoming parallel rays, to concentrate the light down to a single point. Fresnel lenses are mostly used for light gathering power not for precision imaging.

NEEWER offers a wide range of lens adapters. Whether you need an EF mount adapter or an M mount adapter, you can find the product you want here. These camera lens adapters are durable and stable. Precision CNC machining makes the chrome-plated metal mounts extremely durable and well-fitted to your lens and camera. Choose a suitable mount adapter for your camera.

Overview: A Fresnel lens can be looked at as many layers of lenses cut and stacked on top of each other. Creating a lens in this manner provides great collecting or great dispersion power. Lighthouses use Fresnel lenses to project light miles out into the ocean. In this demo, we turn that same lens around to collect and focus sun light into a spot that is so powerful that it will melt rocks. While Fresnel lenses can collect a lot of light in a compact lightweight package, they do not have very good resolution

Optical lens

Objectives: Learn more about a type of lens structure that can be lightweight, for its size, yet very powerful at the same time for the way it collects light.

Optical mounts include optics holders, mounts and holders for lenses and filters, rectangular optics holders, laser head holders, universal plate holders.
